I guess we all would have placed some foolish bets at some point of time in our gambling journey.
For me it has happened multiple times when I just decided to go all in and placed a bet with whatever balance I had in my account.
I have lost it every time I have done that and to be honest, it hasn't made any changes in my gambling style.
Everything is pretty much the same as it was before.
It can happen mostly when you newly started gambling, after losing so much money, you can just get bored and frustrated at the same time and you might just decide to do what ever your mind tells you to do without giving any second thought to what you are doing. At that moment it doesn't matter to you whether you know what you are doing of not, you have submit your self to 100% luck and not any form of common sense application. It happen to me when I first started gambling some years back.
True, I think what you said is indeed a fact that happens and is experienced by most gamblers when they are in that situation, it is true that situations full of desperation can make a gambler take actions that are too reckless or stupid such as betting all the money they have which sometimes they also don't care about the results, but one of the reasons why they take these actions is because usually desperation and decision making based on emotions always want satisfaction without thinking about the possible risks that will occur and this action also more often leads them to regret when they realize it.
And yes it is true that the only thing that can help them in these situations is luck, in the sense that it does not mean that they will completely lose because if it turns out that luck comes at the right time then it will help them and lead them to victory, but the problem is not over, because usually even if luck comes and helps you then you will not necessarily be able to ignore the greed in your mind to continue the gambling session.
