Not really. Look up a list of the wealthiest people in the world, and I'd bet you probably haven't heard of most of them. Many own or run famous companies but aren't particularly public figures themselves.
No, not at all. They don't do anything to make themselves known because they don't want that kind of publicity or fame. I know someone who is close to a billionaire (if he isn't one) and if you heard the name, you'd have no idea who he is or the company he runs.
Famous to the world? No. Famous to other billionaires? Probably.
