There are many people who indulge in gambling activities but I don’t think they gamble as their major source of income. They gamble to add up to their financial status, they play gamble as a side hustle. But in a case whereby the gambling is favoring the person, you don’t expect the person to quit gambling.
Its beneficial for anyone for that matter till the time they end up making money from it and not losing. But generally seen is most of them end up losing some money and if those who just play to win only goes into higher debt or loss as they chase their losses. Only if you play for fun it would not hurt much even if you end up in some loss.
Gambling isn't beneficial for everyone my guy, gambling is not a sure thing to get it's always 50% in any kind it's just either you lose or you win. And from that case, half of people in gambling industry is losing while the other half is winning, so I don't think there is benefit for everyone in terms of the money aspect. Maybe, just a maybe they are getting any from it beside the money for example the lesson from their past lost.
