You have a point but I don't think that gambling companies take students to be their main target, they are just running a business and they are not responsible for anyone's personal gambling activities. People who gets addicted to it are not being compelled of forced, it's a personal decision. The only way to make sure that students don't get tempted to gamble is if they avoid setting up centers close to school environments
And another point is that gambling are not forcing anyone to gamble and they are always doing advert for people to gamble responsibly. And there people that even with education there people that gamble without completing because they are always getting some kind of winning and when you look at some gambling sites you will noticed that it is 18 rated so that way there won't be any form of blaming because the person is old enough to make there own decision. And even people that are addicted choose to be addicted. And we are all looking for ways to make extra money but when doing that we have to make the right decision and do it correctly.
