No such thing... the winners always loses it back...
mathematical certainty. ALWAYS in the long run,
unless they take their winnings and run...
I have not come across any that takes their winnings and run...
they life cycle of a gambler is not WINNING, Stop gambling...
No it is (see sig below...)
There is a "correct way" to gamble though... but that is like
diving without oxgen to harvest oysters... you can drown anytime
you are not careful or when you are weak...
