Did Corey practice, practice, practice? Yes he did. But his stroke and imagination are freaks of nature and in the pool world he himself is a freak of nature. I watched him play 2-8 hours a day, every day, for nearly 4 years. And when you daily say "WTF?" or "thats so gross....", thats a freak of nature.
I hear you and you KNOW I respect your opinion. But having said that the very thing you said, practice 2-8 hours a day is what leads to people figuring out the shots that cause them to be called freaks of nature.
I can jump balls pretty good. Better than most and good enough to get actual applause once in a while for some of the jump shots I pull off. This isn't a talent. There was a point in 1999 AFTER I had already become a decent player and had some hardware to go with it that I found myself needing to know how to use a jump cue.
At my shop in Ilshofen Germany I started to practice with it and I flat sucked. It took me a good week to be able to keep the cue ball on the table. Nevertheless I kept practicing and also thinking about it. By the time we were set to leave for the show I had a decent routine worked out that I could hit pretty consistently to demonstrate the capability of the cue.
And I continued to challenge myself until there was almost nothing I couldn't do with a jump shot.
People actually told me I was talented because of it. I always said no I had to work on all these shots and figure them out. I developed methods to calculate the angles and worked out how much to choke up on the cue to increase or decrease power.
Later I taught all this to anyone who wanted to learn it. Point being that dedication and deep practice leads to insights and abilities that others don't acquire.
I think some people DO have more aptitude for things than other people do. Of course they do. Some people are attracted to numbers, to dancing, singing etc...and if they pursue it then they usually develop into getting pretty good at those things.
Is that talent? I don't know maybe. Our brains are more powerful than all the computers in the world in some ways. So who knows what we are really capable of. Corey is a beast I agree, but I honestly believe anyone who would have been around you and put in the same amount of dedication coupled with curiosity would have impressed you as much as well.
