Absolutely, Perhaps if gamblers can be aware of what is called the house edge which is exactly what you're taking about the more people will begin to adjust the way they gamble. Most addicted gamblers do not agree that they are addicted, which is a big reason why they keep failing and never rise.
Additionally only a few gamblers amongst the multitudes of gamblers gambles for entertainment as it's initial goal but so many gamblers are here for the money which is enough reason to keep losing more money because you can not put you hope to succeed in life with gambling. And perhaps once anyone learns how this house hedges works then the issue of addiction will be so how adjusted.
Unfortunately, many people start their gambler's journey with an insanely huge bet. For example, when my friend received an annual bonus, he went into a room with slot machines and lost all the money.
And when he came to himself, he went to borrow from all his friends, because his only goal was to win back this money. And of course he lost everything that was lent to him. This is the price of ill-considered money management.
Your friend needs help because that is a gambling addiction, and if he doesn't get away from it, he will not have a very bright future I'm afraid. So if you are a genuine friend and you care about him, you should sit with him some day, ask him why he does that, and try to make him understand that it is not good for him in the long run even if he doesn't realize it right now because spending everything you earn on gambling is not something normal people would do.
I know a lot of people do that, they work a whole month only to get their salary at the end of the month and lose it all in gambling. I can't help but wonder how they can do that to themselves, they are wasting their time and their money at the same time by doing this, and they don't even understand what they are doing.
