Gambling were made to make you believe that you can win and earn something,usually who earns always is the house ,the owner some get profit and most users loose all or part of their money at it.The fact is doing dice or betting may lead into a deep loss in a short time the thing i will win again and recover and withdraw wont happen won again then put all again and done,all balance gone.
Yes correct initially you will win some but can't withdraw so again gamble but at the end you will loose all of them again.
