That is the man's believe and not my believe, gambling is not satanic if only you know what you are doing that is doing it right with your habit towards gambling, I completely agree with you that the man has lost so much for him to have come up so such conclusions about gambling being satanic. However, so far people that win are being paid I don't think if there is anything wrong with it perhaps no body has ever been forced to gamble it has always been a deliberate action or activity which is meant to be considered to be for a fun, gambling becomes problematic if only focused are made on maximizing profits which of course has no guarantee, it is either you win or loss.
