Yes ofcourse gambling is profitable ...but when it comes to online gambling or slots ..which are not fair enough and are made just for the casinos profitability .
but even though i have seen winning much coins.
It is only profitable in EV+ games , get your fact straight. There are some occasion that there will be some big winner as well, in the end everything depends on luck. If you are meant to win then there will be nothing that will stop you. Some people just keep dreaming that they could win without actually thinking the risk
