I would call those people as addicts because if they are losing on daily basis then they should be careful with their bets. I know that you can say that no bet is a waste but if someone is always losing the bets then I would definitely consider his/her bets a waste of money. I know sometimes if there is chance of winning and still someone losses then we can say that there was possibly of winning as well but in the case of the ones who lose everyday we can't say something like that.
Yes I agree, it is very correct to say that they have experienced a real addiction there, in my opinion if they experience more losses than usual then the only way that can be done is to reduce their time or budget when they want to gamble again, because I understand in that position there is no way you will be able to stop because emotion has taken over you, and the only way is like I said above. "No bet is wasted" is the same as "no process betrays results", but I would ask if you go through a process to achieve success, when on the other hand there is no success in gambling, this is very appropriate because gambling is just luck. Like you said it's a waste of time, and I think it's ridiculous to keep trying to sacrifice your money for an uncertain win. So the point is if you are losing too much there, and quitting is impossible in that position, then I will say again you can reduce your gambling time and also reduce the amount of money you will bet.
you must remember no matter how much you try if luck does not come then the answer is still you will lose, that's the main point.
I don't think that there is much learning in luck based games because they are entirely dependent on someone's luck and if someone is lucky then he/she will win no matter whenever they place the bets. The experience part is partly true because every single bet make us win or lose and the more we lose the more cautious we become when placing the next bets.
Of course and that's for sure, honestly I also can't understand those who use various methods such as strategies for example just to be able to get a win, and they have great confidence in that method, but in the end it's the same if you lose, you still lose. Gambling is not that complicated, and as you said there is no learning whatsoever to be able to increase the chances of winning there, except learning to be more able to control or control themselves, that's just a very appropriate action and they must have. Honestly, by any means it will still be very difficult to get a victory and it will not affect because it is (real) only about luck.
Oh yeah and I think the fact is that if you win then you get addicted and if you lose then you get curious, that's what really happens and it will keep repeating itself. So be a healthy gambler, do whatever it takes to minimize your losses.
