not disputing that privilege is a thing, but don't you think that if this were true, all people who are born into a middle-class wealthy family and go to a nice school would achieve outlier success?

No; rather the correct question is "if this were true shouldn't we see a greater fraction of privileged individuals achieve higher success rates than we see in less privileged individuals?" Statistics isn't about all-or-nothing outcomes. And the answer to the question I posted is "yes", and the data seem to back that up in numerous contexts from educational attainment to financial success.

The movie Gattaca covers this concept quite directly - I think ironically because it frames the problem as one the individuals involved had no original say in.
