it's true, if you don't want to lose money while gambling the best solution is to stop.(...)
So the strategy you have to do is manage your finances in each game, don't let your money run out in just one game. Because luck when playing gambling is not only in one game, you can get big wins after experiencing several defeats or vice versa.
So if the best strategy is to stop, then why did you carry on and advise people to "manage their finances" to not run out in one game? Will that advice make them any less likely to lose? Or is it just to waste more time together with money?
Betting is all about luck, because the chance of winning is only a few percent of the total money you bet.
That's not true, you could place bets with 99% chance of winning. More important factor to consider is the house edge.
