In the case of betting, strategy cannot always bring positive results to the gambler, he must change the strategy. If you do not win with a strategy, you should not think that the strategy is not good. Sometimes a strategy may work and sometimes it may not be effective. That is why you have to rely on luck to some extent in the case of gambling. In the case of casino gambling, if I use a strategy, I try to use it several times and if I do not get any positive response there, I try to change that strategy. But generally I try to gamble based on my limitations so that if I lose, it cannot have a negative impact on my gambling.
