Disagree. I'm not suggesting the person in question does not have potential or merit and that anyone can do it. It's just that the wealth of a family can pour rocket fuel on that person to enable them to reach their potential.

Yes, that's debatable in each case, everyone has a different story. But it's very likely.

You do get the counterfactual, the plucky upstart who came from nothing. But I'd wager big that that's much rarer and more difficult.
