You didn't mention what might be the most important things successful people have to get them there: a good support network of other successful people, and a good safety net to catch them if they fail (sometimes the same network). I think you can scratch away everything on that list and the network (family, friends, colleagues, etc.) could still help you be successful.

It's like a game where some people get a copy with infinite save/load and helper bots, while others get the raw version where their subscription ends after the first failure. So if I told you "being a successful gamer is about having the patience to load again and again until you manage to hit your target" you'd think I'm crazy, your copy already deactivated after the first missed shot.

The starting conditions are so varied that choosing to define successful people just by looking at the person and nothing else is more of a personality cult exercise than an objectively useful one [0]. And it's no surprise, most successful people love to make that success only about themselves.
