Early life and amateur career
Premlall was born in Durban, South Africa, and began playing golf at around age two. His family later moved from Durban to Gauteng.
In 2018, aged 15 years and five months, Premlall became the youngest amateur to qualify for the South African Open and the youngest player to make the 36-hole cut. He won the Freddie Tait Cup as the leading amateur at the 2021 South African Open Championship. In 2021, he also won the inaugural Nedbank Junior Challenge at Gary Player Country Club.
In 2022, Premlall reached No. 1 in the GolfRSA amateur rankings and represented the International team at the Junior Presidents Cup.
Professional career
Premlall turned professional in 2023, making his professional debut at the Bain's Whisky Cape Town Open.
In September 2024, he won his first professional tournament at the Vodacom Origins of Golf Sishen, shooting a final-round 66 to finish one stroke ahead of Martin Vorster. After finishing sixth on the 2024–25 Sunshine Tour Order of Merit, Premlall earned a DP World Tour card as one of the leading eligible players on the final standings.
Premlall made his Nedbank Golf Challenge debut in 2025 after receiving a personal invitation from Gary Player.
In May 2026, Premlall won the Estrella Damm Catalunya Championship by 14 shots for his first European Tour title. The win came in his 29th European Tour start and was the largest winning margin for a maiden victory in European Tour history. It was also the largest winning margin on the tour outside major championships, one shot short of Tiger Woods' 15-shot victory at the 2000 U.S. Open. The victory gave Premlall exemption on the European Tour through the end of the 2028 season.
