Normally, when someone wins a big wager I usually think "how many times did they played to win this" because sometimes we see like 10x wagers won but maybe that guy played more than 10 times and lost more than he played. However, when we are talking about such a huge odds to win and he still got it, I doubt he played like 10k times, this guy must be in profit by a big margin.

Weird thing is, he is not on the top 10 list, which means dude didn't wagered much enough to go to top 10 and still won or maybe he is one of the hidden ones but if he was hidden than we wouldn't see his big win, which means its unlikely that he became hidden later on, he probably didn't wagered much neither before nor after the big win, that is a huge profit in any calculation ever.
