Gambling has it's ups and downs but to some it's always on the downside for them and one reason is the time they are putting into it, you can't hope to benefit from gambling when you are constantly engaged in it. Some gamblers try to push their luck everyday because they strongly believe that their sin might be around the corner, some also think they have a profitable strategy that can work constantly because they tried it once or two times and it worked. There are no long term profitable strategies don't be deceived by anyone
The only strategy I know to work on long run is to only play with money you can afford to lose, and that is a strategy to just decrease potential losses, anyway. Everything else is just bullshit from internet influencers trying to boost their views to generate profit through traffic. Gamblers must be aware about it, otherwise they will be constantly losing considerable sums of money which they will need later to pay for their expenses.
In worst cases, gamblers borrow money to gamble, expecting to recover it through betting. I watched news recently which brought some gamblers complaining about their losses. One of them lost the wife, as she divorced from him due to his gambling addiction. Another lost his patrimony and accumulated huge debt which must be paid to family members.
I think what all these people had in common was the belief they could make profit from gambling on long run, probably because they were told so by advertisements and of course, due to their personal short term experience with gambling, which tends to be profitable at the beginning. Proper education and awareness are the key.
