I agree. I think a better example (using myself this time) would be the chance of me becoming a highly-skilled basketball player who can dunk the ball and drive the lane, versus me being able to get to a single-digit handicap. Both are a long way off, but I have some of the skills for the latter (and almost none of the former), and there's no specific physical lack that would stop me from playing golf quite well (whereas my knees will put the kibosh on that dunk, all by themselves). Neither is actually going to happen, but one of them probably could.
