That's what we call luck, but you don't have that every time so I can also say that what if you didn't got that chance to win that multiplier? but it's all about how you see your opportunities and how you believe with the strategy that you are using, then plus the luck factor that most of the time gambler always hope that it will back them up.
However, with the strategy used by gamblers, it can at least increase the possibility of generating multiplication with quite a lot of multiples and we get it successfully.
But all of that is only the second factor because as you said that there is still the luck factor that is expected and in every game or bet you can really win because of the main factor, namely luck.
That is luck base games which you need to luck on that and there are no strategy on it but on those card games others are using strategy as this can be use to increase their winning percentage bug again it is always a luck when it comes to gambling unless in sports betting that you have a high chance to win if you know who will you bet on. Also chasing your losses makes you lose more unless you have a ton of money to cover those loses even if you are in lose streak.
