Super shocking (sarcasm). Gamblers are the whales of that industry. The industry is well aware of that and well aware of how much harm they can cause. But their paychecks depend on not knowing so they choose not to. Same as pay-to-win freemium games. Find the whales and milk them for all you can. For every high-spender who can afford it they know full well the other 99 cannot. They know they are ruining some people's…
The worst thing is that gambling companies are free to ban you if you win too much. So if you're still there it's just because you're being milked. There's a a giant market for second hand accounts on betting websites for this very reason.
They are not big fans
