I think talent is innate/inborn. Success is something else, and dependent on other factors. Work ethic, motivation, passion, ambition, desire, economic opportunity/advantage, etc. can all determine the extent to which one is able to translate one's innate talent into success. Some people's talent goes to waste, but the very idea of "wasted talent" or "wasted genius" implies that the talent or genius was there to begin with, regardless of what one did or didn't do with it.
