Sim racing is a good example of this, there have been several drivers who went pro. Sims are used by racing teams and people like Max Verstappen, Lando Norris use sims heavily to improve their race craft.

I do a bit of sim racing and raced against pro drivers.

Athletic ability is a huge part but nearly every sport has a chess component. Additionally, ability to perform under pressure and dealing with stress/anxiety is another part of sports.
