A little guessing the thoughts of casino owners and gambling dealers when they see gamblers playing in their casinos, what might come to mind?
I suppose the casino owners see a picture of a flock of sheep coming to be sheared. 
The name of the business is opening a casino definitely wants to make a profit, while people who come to the casino to seek profit too, although not all, but focus on one object of people seeking profit.
If you were the owner of the casino, what would you think when people like that gamble at your place?
This is a banal conflict of interest: the casino wants to get the gamblers’ money, and the gamblers want the casino’s money. Someone in this scheme will definitely be a loser, because win-win is impossible in principle. The casino has an incomparably better position and a higher advantage, because this casino creates conditions for gambling (room, environment, rules, RTP) and it becomes clear who will lose money.If you were the owner of the casino, what would you think when people like that gamble at your place?
I would think: “here they are, pockets full of money that will become mine!”
