Most pros I know were playing great young or within say five years or so of picking up the game seriously. I don't know anyone that has played for 10 or 15 years and then moved up to a pro level.
My definition of a pro is someone who is a threat to win any event he enters.
I think natural talent/aptitude is a real thing when it comes to who makes it to the highest level.
I agree that natural talent plays a big part but like in golf there are many pro's who have zero chance of winning bigger events
