This is why no casinos are going bankrupted because they know how the gamblers play. They know that there will still be greedy gamblers and they take advantage of it. For me, it is the most profitable business . You can get a huge revenue in the long run but it needs a huge capital to build one.

If only they know how to set limits then the number of gamblers who end up losing will decrease but they don't know how to set that is why they end up losing ALL of their money.
