It doesn’t stop cheating, it just makes cheating require spending a few hundred dollars and dealing with complex hardware setups. This means that relatively few people try.
Non-kernel anti-cheat can be bypassed by software. So it’s cheap and easily available.
That’s the only difference. Kernel anti-cheat doesn’t prevent cheating, it just makes it more expensive.
There’s a lot of study on this topic from the cybersecurity perspective. If you could create an undetectable virtualization layer then it would be used for real-world cyberattacks to steal money and the existence would be quickly noticed by security researchers (and future hardware would include changes to mitigate the vulnerability). It wouldn’t be used for creating aimbots for video games.

Can’t you just use a virtual machine?
That would let you hide things from the kernel anti-cheat but the AC can detect that it is running in a VM and just won’t let you play.
Is there really no such thing as a virtual machine that can’t pretend to be real hardware?
The short answer is no.
