But in real life, people somehow need to gamble too because its just a form of entertainment but in a business way. And you need funds for you to be able to gamble, whether you win or lose in the end.
As a matter of fact, some people gamble for fun, but some people also still see it as a means of earning until they have lost often and often or they become addicted. Nevertheless, gambling should still be for fun and not a means of making money which is not but a means of addiction.
Actually, in this case it is as you say but if you look at other things that make gambling as a suggestion to get money, this is clearly quite naive and usually people like this are addicts and are always obsessed with gambling considering they are thirsty for winning and money and do not accept the word lose there.
Btw now this is happening so commonly which makes it seem like a very normal thing to do as some people are starting to misinterpret gambling as a job.
