You aren't wrong, but the _overwhelming_ majority of "full stack" devs I've worked with only know CSS at the most basic level and have little interest in learning it in depth. I myself have been programming for more than 20 years, doing web dev for almost 15, and I can't find the motivation to learn it well. There are too many technical skills to keep up with and CSS is pretty low down on my priority list. I would prefer to rely on specialists who are experts but companies aren't willing to hire dedicated front end devs.

This is where I'm at. React makes sense to me in ways that plain CSS doesn't. I've learned about 15 programming languages by now, each time out of necessity, but CSS isn't one of them.

Josh Comeau had a good course on CSS, I've used that to learn CSS from scratch.
