I'm not entirely sure what you mean. If you mean that, for example, almost everyone will have the same skills somewhere on their character sheet (ie, most have Athletics, but some at 1 and others at 5) then yes, that's absolutely true. In fact, all characters have *all* skills, though a number of them will have them at Mediocre (0), and by convention we just don't bother writing those skills on the character sheet. And there's a world of difference between someone with a Average (+1) Guns skill and someone with a Superb (+5) Guns skill. Well, more of an
underworld of difference, in the former's case...
Remember also that in this game, even starting characters are fairly exceptional people. This is escpecially true at the "submerged" power level, but even at the "feet in the water" power level characters are described as "enhanced mortals" who can "do stuff that even the best of humanity cannot (but only barely)".
