Need some luck and calculation from that, example with dice game, we can bet small ammount and high payout and increase change rate some % so when we lose too much and hit 1 win we will got profit. Or maybe sport betting is good too when we know who will win depend on how much they lose or strong their team.
But its still gambling, everything can happen in gambling.
Everything could happen but if you use your brain to figure it out then it only require a simple math to tell you that you are going to lose in the long term no matter what. Some people cant figure out this shit and keep playing when they know this , in the end you are going to get profit if you are playing in an EV+ games
