Well, a popular and reputable casino doesn't need to do anything like that since they already have a lot of gamblers and they know that they will get enough revenue to run their business without any issues. However, if a casino doesn't have any reputation and doesn't get a lot of gamblers, they might think of doing unethical things like that to maximize their earnings and keep looting their gamblers out of their money as long as they are not getting caught.

This is why it's much better for gamblers to use casino platforms that are already popular and have a good reputation within the gambling community because they have never scammed anyone or stolen their money by cheating and manipulating the results in games like roulette and others.
