There's "better", and there's better.

Are you better in terms of intrinsic worth as a human being? No, they're just as human as you are.

Are you better in terms of physical strength or stamina, as mattwood asked? No.

Are you better morally than them? (Remember that "morally" includes not just overt acts like theft or murder. It also includes things like pride.)

Or is it merely, as you said in your reply to mattwood, that you think you're better mentally? (And perhaps in terms of achieving financial results.) But of all the possible axes of measurement, why did you pick that one to be the definition of "better"? (Cynically, I wonder if you didn't pick it because it's the one you win on...)
