Maybe? Can't answer the question, too vague.
In Feng Shui, you're one of the baddest people in the world - your kung fu is strong, or your guns seldom miss, or you know the magic of the world. In such a world, you're going to be better than most people on the street in fighting or somewhat... but if you're all fighting types, then you're not going to be better than a doctor is at medicine, or than your cabbie is at driving through Hong Kong. Of course, the bad guys are just about as good as you are.
In D&D, if you start out at 1st level, you're weaker than a lot of the world... but if you hold out to 20th, then yeah - you're 'better' than 95% of the world.
In any superhero game you're going to be better than a lot of folks - you either can pick up a bus, can fly, or whatever. Just as in Feng Shui, though, if you're superman and you need science help, you go to Star Labs, where they're better at it than you are.
