If you will play betting with 1 satoshi every round that's ok. But attention in the moment when you will (if) bet 2 satoshi. If you will do this you will lose for sure. This amount will be always bigger and bigger and one day (again) for sure you will lose all your winnings. Then you will play with your money to win the money you have lost. And it will be another in the days to come your will lose even your money. No one can win against the casino or the online gamble site in long term.
People can win, and it does happen. It is just highly unlikely. There is a huge difference between the two things you are talking about. By your logic, it is impossible to win the lottery, even though someone wins it almost every day.
Someone wins lottery almost every day. But that specific person cannot win it every day. That is a really big difference.
Not when talking about math it isn't. Lets say that the average person has a .001% chance of winning from long term gambling.
Well, think about how many people their are in the world. You multiple that number by the % chance of winning and it turns out that to say at least one person can be profitable from gambling is really really high.
