First, note that the biggest winner is reasonably likely not to be a good player. You might consult Sklansky's bit on why the guy winning after day one of the WSOP never wins the tournament, to develop your intuition for this sort of thinking.

Also, a lot of the best players play LAGgy live. In particular, the ones who cut their teeth online tend to. It's a good way to play against weak competition.

So, in short, the guy who wins the most tends to be LAGgy because the best, and the highest-variance of the worst, both play that way.
