That is true. Compared with our childhood, current kids have way more sources of information. Parents hide that they gamble, while kids already know what gambling is and gamble secretly 
Everyone stay silent until bad things happen. I was always trying to say that educate and explain is better than bad or hide. Why everyone think, that if a kid saw or knows what is gambling, he will immediately run to gamble? And if he really did that? Is that really that bad if he has lost all of his money? Better he learns that bitter lesson now, than he is 25 and he looses salary, takes loan and goes into more problems.
I dont think that a kid will use gambling as a solution if he lack money for something or wants to become rich. He has parents after all, who must carry him on from 0 to 18 yo. But later give more of a support, than fully maintain his life. Well, a kid might also be simply stupid. Gamble all the money, steal, get involved into criminal and etc. But that is not because he saw his parents gamble. These are his genes
The availability of the internet and smartphone devices is making harder for parents to protect their kids from having access to all kind of activities that could be harmful to them, so being open about those dangers seems like the best strategy they can use, however it is important to not underestimate the dangers gambling present for underage people, as this is not only about the money that can be lost, it is a very well established fact that those that suffer from addictions began those behaviors as kids or as teenagers, while an adult person that began to gamble has very low possibilities of ever developing an addiction.
