I have even seen beer drinking bars night clubs that are close to learning center. And as you said, each student knows why they are in school. When I was in school, I didn't attend any of those things plus gambling. And even if I count the time I visited gambling centers it would be very few occasions.
And even though the gambling centers are not close to the learning environment those serious gamblers would still go there and play games. And when it is far they would prefer it because nobody would see them because it is far. But there is disadvantages and advantages of being far and close to the school. You attend class on time if it is close or you attend class late if it is far.
I will go even further, some universities actually have bars inside the universities, with activities, and cheap prices for students.
It's not always a bad thing if you drink alcohol in moderation, and can actually help socially.
Maybe it's the same with gambling, although most gamblers I've seen are usually by themselves spending a lot of money. It's only a few that go in groups to socialize, maybe because it's too expensive to keep doing it.
As for it is not even where the gambling center is located because those people are looking for a populated areas to establish their business and if they asked the school authority and they permit them to run their business class to the school or in the school, if it will not affect learning then there is no big deal.
I think opposite a Law school in one of the state I have visited in Nigeria has a gambling center. And everything goes well.
