It's not that simple. The real problem is that Valve allows items to be sold in markets outside of Valve's control which allows third party gambling websites to operate. And you guessed right, they basically don't care about your age. Valve of course knows this but won't do anything, because they make profits off all transactions happening in third party markets. Plus the whole professional CS tournament scene is sponsored by these predatory casinos. Coffeezilla did an in-depth piece on this: https://youtu.be/q58dLWjRTBE
