"Gambling can be profitable in the long run! It is possible!"
"Gambling is not profitable 90% of the time! It is possible!"
Yes, of course it is profitable. But most of the time it is NOT.
It is depends on how are you played on each gambling site. Play slowly and dont be greedy that is how people can manage to profitable in long run but until you achieve that goal you must stop it no matter what or you will be on losing again. That is why you need self control there
Everyone on this site needs a dictionary.
It is POSSIBLE to win gambling on -ev bets (blackjack, roulette, dice) whatever.
That does not mean it is PROFITABLE LONG TERM. Words have meaning.
If you get a powerball ticket on your 18th birthday for free and win 100 million dollar jackpot and never spend a cent gambling for the rest of your life you will have made money on -ev bets. That doesn't mean powerball is profitable long term.
Self control has nothing to do with it, if a bet is -ev, it isn't profitable long term, if it's +ev it is.
