In 2015, Gall became the Austrian junior champion in road racing. In the autumn of that year, he competed at the 2015 UCI Road World Championships in Richmond, Virginia, United States, and won the title of junior world champion in road racing.[7][8] Upon his return from the United States, he was welcomed by around 1,000 people in his hometown. He received a cycling scholarship, a driver's license course, and a new racing bike.[9]
In 2016, Gall won the junior competition Trofeo Dorigo Porte, and the following year, he received a contract with Development Team Sunweb. In 2018, he won the Austrian National Road Race Championships in the under-23 category.[10] In March 2019, he achieved his first success in an elite race by winning the second stage and the general classification of the Istrian Spring Trophy.[11]
AG2R Citroën Team
After three years in the development team and two years in the WorldTour squad of Team Sunweb/DSM, Gall announced in 2021 that he would move to the AG2R Citroën Team the following year.[12] Originally, his contract with DSM was supposed to run for another year, but due to ongoing tensions between different riders and the team management, Gall terminated his contract at the end of 2021.[13]

In 2022, Gall, as part of the AG2R Citroën Team, achieved sixth place in the overall classification of the Tour of the Alps.[14] He was then named in the startlist for the 2022 Giro d'Italia, his first Grand Tour.[15]

In the 2023 Tour de Suisse, he finished 8th overall in the general classification and fourth in the mountains classification. In the process, he won Stage 4 — his first victory as a pro — and finished second in stage 3.[19]
He was named in the AG2R Citroën Team's startlist for the 2023 Tour de France, marking his first ever participation in the race.[20] For the first time in his career he wore a classification jersey after getting involved in the breakaway on stage 5, and earning enough points to take the lead in the mountains classification after being the first to crest the summit of the Col du Soudet.[21]
On 17 July 2023, Gall won Stage 17, the Queen Stage, of the 2023 Tour de France.[22]
