It's been pretty well covered, but I'll reiterate a few points.
Few are willing to spend the time, money and effort (read work) to become above average, let alone very good or exceptional. Many competitive shooters are very good or exceptional. Read up on the old time exhibition shooters, they were just flat stunningly amazing, and they did it in front of hundreds of people at a time on a regular basis. Hitting small objects tossed in the air isnt "trick" shooting (and no, the real deals dont use shot loads), its outstanding shooting, and it's real. Jordan was reportedly able to hit 5 asprin tablets thrown in the air. Other exhibiton shooters have been able to consistantly shoot through the hole in a washer thrown in the air, with tape over the hole to prove it. Some people are also just real good at certain things, having a natural aptitude for some thngs, and having outstanding eyesight helps.
Just because the local crowd, or any individual can't do it doesnt mean it can't be done. Spend enough time and effort getting good at somethng, and you may amaze even yourself, but be prepared for others that can't do it to call you a liar.
Some people also simply aren't intereted in competition. Just because they can do something well doesn't mean they are interested in playing that particular game with it. They dont have to prove anything to you or anyone else, they know what they can do, and enjoy it for its own sake. I knew one such shooter. He was quite capable of hitting silver dollars thrown in the air, making 300 yard hits on rocks the size of a gallon jug, and shooting cigarettes out of people mouths, and I'd seen him do those things, as had many others. He did some local exhibiton shooting over the years, but had absolutely no interest in shooting competions of any sort (and he would have cleaned house had he wanted to), he simply loved shooting, and the history associated with it. He shot everything with a Colt SAA 45, all one handed. He was probably not quite as good as some of the well known exhibition shooters, but to say he was pretty good may be an understatement. I shot with him a few times, and saw some of is exhibtion shoots. He inspired me to try harder, and at things I hadn't pushed myself to do before. For my part, I take the naysayers with a grain of salt, not the other way around.
I agree with Mr Borland, competition can be a very good motivator and teacher. It doesnt appeal to some, tho if they have the motivation, can become very good, if not outstanding.
