I think people don't understand that there is no strategy in gambling. Gamble but consider your spendings on it as an entertainment expense. Got luck on your side and won? Good. If you don't you still had fun.
It’s just that people have a lot of strategies to use but certainly, they don’t work in gambling. The only weapon that we should have for gambling is luck. Without it, you’ll never be good enough in gambling. That’s why we often heard that when someone hits the jackpot prize, a lot of people will make a compliment that he/he must be lucky enough. It’s always luck with some sort of skills that comes winning in gambling.
Well, in this condition, the strategy that was actually carried out was just being sure and suggesting, I think in this case because it's true, as you say, nothing can really have an effect because the main factor, of course, is luck.
But on the other hand, when talking about strategy for several game conditions, such as in a sportsbook, for example, it can still be done to minimize the results of defeat, even though luck is important, the strategy for not betting carelessly is also quite important here.
