This man actually has some sense into what he says: Dont gamble.
It is interesting he was banned for life in the casinos and he says that the house is rigged.
That we knew, but how is it rigged?
And how was he able to win?
He has probably discovered a secret mathematical method to win, or maybe he found the program all casinos use to cheat a pattern.
Or he is just good at reading people and playing poker.
