You are correct, we cant really assure our selves that we could make a stable income on gambling since its just a matter of luck game and in the end it has higher chance on lossing all your money on the long run. I believe most of gamblers would definitely have more loss compared on their winnings.
That's true, most of the time we can lose in gambling than winnings. If we win, it's just happen once or trice but losing is more often, so always think twice, what is your purpose of playing this kind of game if we cannot get some benefit without any assurance?
People are just used to play on those gambling that faces the house edge. The output in playing here is clear so why people keeps continuing to play on this type of games?
I don't believe that we can lose more in gambling than winnings if they will choose to play on those strategy gambling games instead. There's no way we can have lose a long streak here with a martingale type of betting.
Try to play gambling and then tell me what is happen in your game or tell me the result of your game before you tell me that you don't believe that we can lose more in gambling than winnings.
The result of all my games are most losing than winnings. Yes we can win in gambling also but MOST OF THE TIME losing is more often than winning.
