I have heard the advice that you should only use money you can afford to lose for gambling. I say that this is more theoretical than practical. Literally no one has money that they can afford to lose. I feel that money for gambling is a matter of opportunity cost. You either use the money for gambling or use it to meet a need.
What you say, maybe it's true, the facts on the ground are different from what we are talking about, theory and practice are two different traits, but behind all that those involved in gambling have different characters and traits, In my opinion, there are levels of people who gamble, from ordinary gamblers to high class gamblers, from entertainment to high level addiction, that's what differentiates the funds used for gambling.
For those on the verge of addiction, they use unlimited money to gamble, from savings, selling property, to gambling, However, there are also those who use money to gamble with the money ready to be lost and there are also those who are unemployed but they are affected by gambling, By not having money, they don't think much about what money they use for gambling in the hope of winning and making a profit, it doesn't matter where the money comes from, the important thing is money.
Of the many cases we have seen of someone using money to gamble, everything that is said is true, because a thousand people have a thousand ways of using money for gambling, losing money, entertainment, profit, making a living and so on, all of them are true.
