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
I do not think there is a difference, it will only take you longer to play in an EV+ game but eventually if you commit a wrong decision you will have your winnings fly away. Anyway there is fun in profit and regret on losing, so I always play for profit and reap the fun as bonus. With this in mind, I alway made myself aware of the in and outs of the bankroll and alway check if it is time to quit or can still continue with the current bankroll status.
