Imagine your son, who just turned 18, comes to you, saying, "Dad, I would like to learn how to bet on soccer." He asks if you can explain the basics, like understanding odds, analysis techniques, and the risks involved. What would you do

I know that, as a parent, you want to support your son’s interests but also worry about the potential downsides of gambling, which is normal from my point of view (well, I think teenagers may become addicted to gambling more easily than adults).
My question is: Do you take this opportunity to teach him about responsible betting, or do you try to steer him away from it? Also, if you are still supporting him financially, would you allow him to use the money you provide for betting? the money you work so hard for...
P.S.: Whether you’re a parent or not, you are welcome to share your opinion! 
I think to bet or just pick with no money involved is accepted but if it's the other way around I guess that would be frown upon to do so. He surely will get the jist of it even if you've just teach the basics as I will not really spoon-fed him, learning by doing is my approach when it comes to things like this.
At age 18 I'll surely have been conditioned him of what's responsible or not even at handling finance, teaching him just recently is surely a lacking parent skills. Most academic institutions doesn't teach financial management and I guess as a modern parent we need to destigmatize that once and for all. We don't have to be ashamed teaching them that kind of skills because it's really hard to be poor, the world is so cruel to poor.
