If there are thousands of players like that, surely they must play each other frequently, ergo they must occasionally play each other while each competitor is in dead stroke, in which case both players WILL WIN regardless of how the other shoots?!? That would be quite some match. How do they decide who takes home the money?
I realize that exaggeration is a fact of life when you're listening to people talk about pool expertise (or fishing stories, or how fast their old project car used to run 1/4 mile, etc.) but I agree with cuetechasaurus about abuse of the concept of "unbeatable". It obscures the meaning of what you're trying to say because it can't possibly be true.
