I write vanilla CSS in 2020, but I suspect you're right in a "most people" sense. Still, I'm biased toward longer-lived approaches, meaning that whenever I can make it practical, I try to build with vanilla HTML, CSS, & JS with as few other technologies & libs as I practically can. Even my final HTML tends to be quite human-readable.
Again, this won't work for many projects, but the point of it is long-term maintainability. I assume that most of what is built into major, recent browsers will have the longevity of bottled wine, while technologies outside the browser will be more like fresh grapes. If I want the site itself to be more like the wine than the grapes, doing something with it years from now shouldn't require a tool that no one has used for years.
But it's not how long they've been around, it's whether they're built into standard browsers. Presumably, CSS variables can never be removed from standard browsers. They are permanently available in the web "toolchain". SASS can be replaced by something else. There will be workarounds, but it will probably be more of a problem.

To be fair sass variables have been around much longer than css variables.
