those gamblers who are incapable of accepting losses when they gamble are naive and ignorant because every gambler is meant to acknowledge the fact that gambling losses are inevitable and unavoidable, and gamblers are meant to lose more than they even win, so if a gambler is still crying over losses or is unwilling to accept losses, then that gambler isn't really ready to gamble because they'll keep chasing losses and lose more on the process. Learning to accept losses will potentially help a gambler take calculated risks and will critically consider the magnitude of every decision before taking it.
That's right, if you admit that you can lose before you place a bet, then the bet will be more thoughtful, I won't bet too much because I know that I can lose. And then I just need to calculate the risks correctly, the higher the odds, the less I bet, but with small odds you don't need to be too self-confident, because small odds are not always winning either. Therefore, it is better to bet as much as you don't mind losing, this is the best solution.
