Someone with talent or skills that serve an activity well learn faster. Hard to say they have a higher ceiling. I have studied those that were world class since I was a child, world class at almost anything. A man was an olympic gold medalist shooting a pistol one handed duelist style. He lost his arm in an accident and came back to win another gold medal with the other hand. There are many stories of world champions overcoming great adversity to become champions again. Sicknesses or injuries that kept them in bed for many months and left their bodies wasted away. Having to learn to walk again. Coming back to win. Just watched a runner doing a face plant in a fairly short race, 600 meters I believe. She came back to win.
Speaking for me personally, I was one of the worst pool players ever! It took me six months of near nightly effort to win more beer than I lost in bars. Once I started winning more than losing I kept raising the level of competition I played against and kept winning. The time came that when I was holding home field advantage few road players could even break even. I could take the other local shortstops.
As much as anything else it was simply a refusal to lose. I was known as slow and clumsy as a child and adolescent. Few noticed my timing and accuracy. In later years I selected things that I was best able to compete at. No way I would be a distance runner but I beat one on the pool table. I ran very well, with a stock car or sprint car wrapped around me! Later in life I found a gift for shooting pistols fast but I didn't try to run and gun. I shot benchrest rifle too, that took a lot of expertise but only a bit of talent.
Being good at something is a matter of liking it enough to work like hell at it. One gift I did have as a teenager and young adult, I needed very little sleep. I could go twelve or fourteen days on two hours of sleep a night, sleep twelve to eighteen hours and repeat the cycle. This let me work or go to school and still have plenty of time for pool and other things like building my race cars. When I was ready to sleep I was ready! I have slept a few feet in front of concert amplifiers or with stock cars passing a couple three feet from me while I slept on the inside pit wall with a foot dropped on either side of it to keep from falling.
You can do almost anything at a high level if you want to badly enough. There is so much information available now it is almost easy to play pool very well. The catch is that so many people can learn to play very well that it is harder than ever to cross the tiny gap between "very well" and elite, top handful in the world.
