I agree, and I've thought for a long time that "natural talent" is usually just "natural curiosity" that has been given enough time to grow into something bigger. After all, if you regularly spend your attention focused on something, you'll inevitably become better over time. I think a lot of topics that people consider to be "impenetrable", like programming, science or math, can be tackled with this attitude.
I don't play golf, but I imagine there are so many minutiae, from driving, choosing which iron to use, putting, stance, hand positions, comparing clubs of the same type from different manufacturers, and same for golf balls. Each has a breadth and depth to explore as you get more and more into that topic.
I'm willing to bet the people that rise to the top are the people who love to tinker with all those parameters, not necessarily because they know it will make then X% better, but because they just want to see the effect.
