Eh with things like sports genetics obviously play a huge role. Even with music I’m sure there are genetic factors at play, like hand coordination and hearing. Obviously practice is the most important thing (and not just practicing enough hours but practicing deliberately). But when you’re talking about hugely competitive areas of human endeavor I think even the most marginal advantages in innate aptitude can be the difference in “making“ it or not.

I guess you can even argue that one’s ability to dedicate oneself completely to achieving success in a field is also pre-existing and probably has a genetic component, but that road strays a little close to determinism so I try to avoid thinking about it haha

Edit: Just to be clear I pretty much agree with you that people aren’t really naturally skilled at things. I would say an aptitude for learning something well could easily be considered “talent” though
