He started playing tennis at age 11 at the Vitacura Sport Frances golf club.
Ríos reached the semifinals of the junior French Open in 1993 without dropping a set, where he was defeated by Roberto Carretero-Diaz in straight sets, and won the junior US Open in 1993 while only dropping one set during the entire tournament. He also won his first Satellite tournament in Chile.
Ríos turned professional in 1994, finishing 1997, 1998, and 1999 as a top-ten player. Ríos won a total of 18 top-level singles titles and one top-level doubles title during his career.
In May 1995, aged 19, Ríos won his first tournament title in Bologna defeating Marcelo Filippini of Uruguay 6–2, 6–4, and breaking into the world's top 50 for the first time. Then in June, he won at Amsterdam in both singles (against Jan Siemerink, 6–4, 7–5, 6–4) and doubles (with Sjeng Schalken) and won the tournament in Kuala Lumpur against Mark Philippoussis 7–6, 6–2. He also reached the final of his home country's ATP tournament in Santiago. Ríos ended the year ranked No. 25 in the world.
In 1997 for the first time in Ríos' career he reached the quarterfinals of a Grand Slam tournament at the Australian Open and again at the US Open. He also won his first Masters title at Monte Carlo; after a first round bye, he beat Andrea Gaudenzi, Albert Costa, Carlos Moyá, Magnus Larsson, and, in the final, Àlex Corretja, 6–4, 6–3, 6–3. Two weeks later, he lost in the final of the Rome Masters against the same Spaniard. Other successes for the year included the quarterfinals (again) in the Stuttgart Masters and the finals in Marseille, Boston, and (for the third time) in Santiago. Ríos had a very consistent 1997 season, being the only player to reach the fourth round or better on all Grand Slams. Ríos went as high as No. 6 during the year, and ended the year in the top ten for the first time, being No. 10.
The year 1998 brought the peak of his career, when he reached the No. 1 spot in the world. He won the tournament (the first of the year) in Auckland, New Zealand, against Richard Fromberg, then reached the final of the Australian Open, beating Grant Stafford, Thomas Enqvist, Andrew Ilie, Lionel Roux, Alberto Berasategui and Nicolas Escudé before losing to Petr Korda in a lopsided 2–6, 2–6, 2–6 that lasted 1 hour and 25 minutes. The following months brought successes such as the title of the Super 9 (the current Masters Series) at Indian Wells, where he defeated British Greg Rusedski in the final.
In June, at Wimbledon, Ríos was upset at first round by Francisco Clavet. On August 10, however, Ríos recovered the No. 1 spot for another two weeks. In September, he lost at third round of the US Open to Magnus Larsson. During this season, Marcelo also won the Rome Masters against Albert Costa by walkover in the final, Sankt Pölten beating Vincent Spadea, the Grand Slam Cup against Andre Agassi, and Singapore against Mark Woodforde. Furthermore, he reached the quarterfinals of the Stuttgart Masters and Paris Masters. Ríos in 1998 won seven titles, including three Masters Series titles, and reached the final of the Australian Open. On July 27 of that year, he reached the maximum number of points achieved throughout his career: 3719 (by the scoring system used prior to the year 2000). He ended the year ranked No. 2 behind Pete Sampras, who topped the world rankings for a sixth consecutive year.
Ríos met Costa Rican Giuliana Sotela in September 1998 while he was training at the Nick Bollettieri Tennis Academy in Florida. Ríos and Sotela got married in December 2000 in Santiago. They have a daughter, Constanza, who was born in June 2001. In March 2004, the marriage ended in divorce, which legally took place in Costa Rica, as Chile did not allow married couples the right of divorce until November 2004. During 2004, Ríos worked as a sports commentator for a radio station in Chile.
At the 1998 ATP Tour World Championships (Tennis Masters Cup), Ríos withdrew at round robin stage after playing the first match. He was replaced by then world No. 11 Greg Rusedski.
At the 1998 Eurocard Open (Stuttgart Masters), Ríos withdrew prior to quarterfinals.
Since 2000 until the end of Ríos' career on the main tour, he was not able to keep up his level of play to the standards he set in the 1990s, as it was marked by repeated and disabling injuries. He still won the tournament of Umag, Croatia beating the Argentine Mariano Puerta in the final. He also reached the semifinals at the Hamburg Masters losing to Marat Safin. Ríos finished the year No. 37 in the world.
In 2001, Ríos won the first tournament of the year in Doha. However, his performance in the following tournaments was weaker, weakened by an ankle operation, which resulted him to drop out of the top 50 in the world for the first time since he was a teenager. In September Ríos won another title, this time in Hong Kong, defeating Rainer Schüttler in the final. Ríos decided to return in October to play a Challenger event in Santiago and defeated Edgardo Massa in the final, in an effort to end his curse of not winning an ATP tournament at his home country. He also reached a doubles final in Scottsdale. Ríos ended the year as No. 39 in the world.
At the 2001 Monte Carlo Masters, Ríos withdrew prior to second round.
In early 2002, Ríos had some good results, but a back injury prevented him from continuing the season successfully. It was the same injury that he had had two operations with already, and finally prevented him from returning to a competitive level. His best results were the quarterfinals at the Australian Open, the semifinals at the Miami Masters, and the final in the Stockholm tournament playing the Paradorn Srichaphan. Ríos would finish top 25 in the world for the first time since 1999 at No. 24, but without managing to recover from injuries that beset him since late 1999.
In Viña del Mar tournament (formerly Santiago tournament) Ríos reached the final, losing to Spaniard David Sánchez. This was the fourth of the four finals he participated and lost in his home country. However, representing Chile together with Fernando González and Nicolás Massú, he won the World Team Cup in Düsseldorf. The same year he also won silver medals in singles and doubles with Adrián García in the 2003 Pan American Games. In May, Ríos played his last ATP-level match, losing in the first round at Roland Garros to Mario Ančić, retiring at 1–6, 0–1. In 2003, Ríos played very few tournaments, in most of which he had to withdraw. This resulted him ending the year as No. 105 in the world, his worst year-end ranking on the main tour yet.
In 2004, six years after claiming the world No. 1 ranking, and after a long absence from the tour, Ríos returned to competition with a victory at a Challenger Series tournament in Ecuador. He played his last competitive match in early April 2004 at a Challenger in San Luis Potosí, Mexico, where he retired in the round of 16.
Finally, on July 16, 2004, after years of constant injuries—and at just 28 years old—Ríos announced his retirement from tennis during a press conference in Santiago. He organized a farewell tour across his home country, travelling through several cities, meeting with fans, offering tennis clinics, and playing friendly matches with international and local tennis players such as Petr Korda and Goran Ivanišević. The tour ended on December 22, 2004, at a soccer stadium in Santiago, where he played his final tennis match of his career on the main tour against Guillermo Coria.
In April 2005, Ríos married model María Eugenia "Kenita" Larraín, a former fiancée of football player Iván Zamorano. The couple subsequently experienced a very public break-up in September of the same year after an incident in Costa Rica in which Larraín was injured when Ríos allegedly threw her out of his car while he was driving to visit his daughter. Ríos claimed that marrying Larraín was "the biggest mistake of my life."
On March 29, 2006, Ríos, aged 30, debuted on the ATP Champions Tour, a tour for former tour players, having met the requirement of at least two years after retirement. At his first tournament on the tour in Doha, Qatar, he defeated Thomas Muster, Henri Leconte, Pat Cash, and Cédric Pioline to claim the title. The following week he repeated, this time winning the crown in Hong Kong, where he won the final against Muster. Ríos won six tournaments in a row, adding Algarve, Graz, Paris and Eindhoven to the above. His inclusion on the senior circuit caused mild controversy, as he was significantly younger than many of his fellow competitors. He ended the year as No. 1, winning a total of six tournaments and holding a winning streak of 25 matches, achieving the record of being the only player in history to be No. 1 in the world as a junior, professional and veteran.
Ríos did not take part at the Champions Tour in 2007.
On March 30, 2007, Ríos played an exhibition match in the Movistar Arena against Andre Agassi, both as a way to commemorate the match where Ríos rose to world No. 1 and as a way of having the American play in Chile.
In 2008, Ríos came back to veteran's tour where he won the tournaments in Barcelona and Algarve. On June 22, 2008, he was defeated by Pete Sampras in the final of a seniors tournament in São Paulo, Brazil. Ríos ended the year as No. 3 in the veteran's world rankings.
On June 24, 2008, Ríos defeated Sampras in an exhibition match that commemorated the 10-year anniversary of having reached the No. 1 ranking in the world.
In May 2008, Ríos married Paula Pavic. They have five children together, daughter Isidora (born December 2008), daughter Colomba (born June 2010), and also triplets, which are a son named Marcelo jr. and two daughters named Antonella and Agustina (all born December 2011).
In March 2008, on the tenth anniversary of Ríos reaching the No. 1 ranking, journalist Nelson Flores published a book in Spanish titled El extraño del pelo largo (The strange man with long hair), recounting his experiences following the player from his junior days up to his ascent to the top of the ATP singles ranking.
In May 2014, Ríos said in an interview to El Mercurio that he could have Asperger syndrome. On November 17, 2016, he confirmed in an interview to Chilevisión that he was diagnosed with Asperger twice in his life, as a child and during a Davis Cup tie, but he did not care that much until the 2014 interview.
Following successful elbow surgery in November 2018, Ríos announced a comeback as part of his desire to become the oldest ever winner of a Challenger tournament.
On December 21, 2018, Ríos defeated Nicolás Lapentti 6–4, 5–7, 11–9 in an exhibition in Chile.
