That is not true. If Bill Gates grew up like that, he would've been labeled a "self made success" even making $50k yearly. He is from a rich background and thus we have to compare him to his peers - and he definitely is successful and that success is self made compared to anyone from upper middle class - but that doesn't have to do anything with the fact that Bill Gates wouldn't have been able to do what he did if he didn't have rich background (is it even practically possible?).
