Very regrettable something, sometimes when your First predictions comes out to be the winning bet and your other addictions now brought you down to lose the entire games, although risk sometimes pays and when it does, the best we can do is to be thankful and happy for that, but if we did lose, then it means we need to bear the pain and move on and next time we do and take such risk with causion to avoid such outcome even though we can't totally avoid loses in gambling since loses is part of gambling and the way casino makes they own revenue to continue with they operations.
Yes you are right, maybe because of the influence of greed that will have a bad impact in the future, such as knowing that it will be risky, still continuing and betting and all there is is regret due to the defeat that will be received.
Of course as a gambler, good or bad results cannot be avoided easily, but what we can do is minimize it early on so that it does not have a very high impact by being careful every time you act in gambling as you said.
