Although Trump had won eight ranking titles by the end of the 2017–18 season, many snooker analysts believed that he had underachieved up to that point in his career, given his talent. In the 2018–19 season, his form and focus notably improved. He won ranking titles at the Northern Ireland Open and World Grand Prix, won his first Masters, defeating O'Sullivan 10–4 in the final, and completed his Triple Crown by claiming his first world title, defeating Higgins 18–9 in a final that featured 11 century breaks, a record in a professional match. With his World Championship victory, he became the first player to win over £1 million in prize money in a single season. During the 2019–20 season he set a new record by winning six ranking titles in a single season. In the 2020–21 season, he won a further five ranking events. Trump was voted the World Snooker Tour's Player of the Year for three consecutive years from 2019 to 2021 and was inducted into the Snooker Hall of Fame in 2021.
