Your resources is how well you can solve your problems with money. As an example, certain implementations of Batman never really use Wayne's billions of dollars to actually solve any of Batman's problems, so you could have a Batman stat sheet with a very low resources on it.
Or, for an example from the books, Michael has a lot more money that Harry does, since he has a house and can feed his family something other than dog food, and so on. But Michael never seems to solve his problems with money, so Michael doesn't have any more points in resources than Harry does.
