Why will anyone regret in a game that winning comes by chance and not by our own doing. No matter the strategy that you use when gambling, only luck can give you a win, which is the main reason why one needs to accept the outcome of his bet without regrets and enjoy the fun. Currently, I don't regret anh of my past losses because I have accepted my fate.
That's something every gambler must accept. Those who still regret losing at gambling are simply not suited to gambling because they haven't yet accepted the reality of their own lives. So, what you said is true, because every gambler must be willing to accept defeat without regret, because it's an unavoidable fact for anyone when gambling. And I'm also surprised that some people still regret losing, even though no one has a guarantee of continuing to win at any form of gambling.
