Van den Bergh's first round match at the 2017 World Championship went to a deciding set and was on throw, but he missed two darts at double eight to send it to a tie-break, allowing Cristo Reyes to step in and win 3–2. At the end of the year, Van den Bergh became World Youth Champion by defeating Josh Payne 6–3 in the final. He would defend his title the following year by defeating Germany's Martin Schindler in the final.
