All three were born in 1975, Williams on 21 March,^[1] Higgins on 18 May,^[2] and O'Sullivan on 5 December,^[3] and all turned professional during the 1992–93 snooker season. They have become known for their collective dominance of the sport, as well as their longevity as top-ranked players.^[4][5]

The Class of '92 has collectively won 98 ranking titles, with O'Sullivan having won 41, Higgins 31, and Williams 26. All three players have won each Triple Crown event multiple times, for a combined total of 39 Triple Crown titles.^[6][7] At the end of the 2021–22 snooker season, after 30 seasons on the professional tour, all three players were ranked within the top eight in the world.^[8] In terms of their collective dominance and longevity, O'Sullivan has compared the Class of '92 to the Big Three of Novak Djokovic, Roger Federer, and Rafael Nadal in men's singles tennis.^[9]

At least one member of the Class of '92 featured in 18 of the 25 World Snooker Championship finals contested between 1998 and 2022. The three players have won a combined 14 world titles, three by Williams, in 2000, 2003, and 2018;^[10] four by Higgins, in 1998, 2007, 2009, and 2011;^[11] and a record-equalling seven by O'Sullivan, in 2001, 2004, 2008, 2012, 2013, 2020, and 2022.^[12] As of the 2024 World Championship, they have made a combined total of 88 appearances at the event's main stage at the Crucible, with O'Sullivan having featured 32 times, Higgins 30 times, and Williams 26 times.^[13][14] All three players have reached the semi-finals of the World Championship on three occasions: in 1998 (with Ken Doherty), in 1999 (with Stephen Hendry), and in 2022 (with Judd Trump).

The Class of '92 has collectively compiled over 2,850 century breaks in professional competition, including 31 officially recognised maximum breaks, of which O'Sullivan has made 15, Higgins 13, and Williams 3.^[8] From the time Higgins first became world number one in May 1998 until the end of the 2023–24 snooker season, the Class of '92 players held the top ranking spot for a cumulative 5,334 out of a total 9,499 days.^[15]

More than three decades after turning professional, the Class of '92 continues to win events and has set longevity records in the sport. As of January 2024, O'Sullivan holds records as the oldest winner of all three Triple Crown events, having won his seventh world title in 2022, aged 46 years and 148 days;^[16] his eighth UK Championship title in 2023, aged 47 years and 363 days;^[17] and his eighth Masters title in 2024, aged 48 years and 40 days.^[18] O'Sullivan has made more appearances than any other player in the final stages of the World Championship at the Crucible, with 32 as of the 2024 event. During the 2023–24 season, Williams won the 2023 British Open aged 48 years and 194 days and the 2024 Tour Championship aged 49 years and 17 days, making him the second-oldest player to win a ranking event, after Ray Reardon, who won the 1982 Professional Players Tournament aged 50 years and 14 days.^[19] When Williams faced O'Sullivan in the 2024 Tour Championship final on 7 April 2024, the two players set a record for the highest combined age in any ranking snooker final.^[20] Higgins has spent the most consecutive seasons ranked within the world's top 16 players, his record standing at 29 seasons at the end of the 2023–24 season.^[8] Higgins also holds the record as the oldest player to make a maximum break in professional competition, achieved at the 2024 Championship League when he was aged 48 years and 268 days.^[21]
