That matches my experience too. SVN and CVS was very common as far as I remember. More developers probably use version control now than before, but version control was considered part of "best practice" before git was released.

There were of course places that were late to switch. I remember one of my old work places used P4 due to legacy in the CI/CD pipelines, but many teams kept a "shadow" git repository in Bitbucket with a bridge to P4. After a while, the company finally switched to Github Enterprise

SVN took over the hobbyist area rapidly due to its workflow/UI similarity to CVS, but P4 held fast professionally until at least 2015, as well as Source Safe if you were an MS shop. (And conservative places never switched off CVS at all.)
