I'm a school admin who works in this space so I know this well. First, sites do have to do exactly what you mention and if they knowingly collect info from 13 year olds and younger, they must implement all sorts of additional privacy controls. Google, for example, was sued (but paid a puny fine) for really not doing anything at all to ensusre it was heeding to this in YouTube. If you've ever uploaded a YouTube video, for instance, you'll now always be asked to confirm of whether or not its target audience is children, the impact of which has to do with how YouTube is able to monetize or provide advertising with that content. But the gist of it is this: Between people just lying and a non-trivially large group of parents just simply not caring, the problem is quite unsolvable. I literally do several workshops and also meet with parents individually to discuss their child's development as it relates to technology. I preach the almost comical inadequacy of giving your 7yr old a smartphone, talk about COPPA and related laws, and explain what we know about young children and mental health when it comes to social media. With YouTube, we've presented numerous articles talking about how the automated algorithm not only hijacks their child's attention for the pure intention of generating profit but also has been shown to be a tool that can easily lead to radicalization. They don't care. I don't think I'm THAT bad at my job, but the reality is there is a small group of like-minded families who independently share this view, but the other 95% do not care. At all. The economics of it, in the real world, just don't work out in favor of people who, like you and me, think this a serious issue.
