Git is over 20 years old at this point. If somebody is in their 60s now, they were in their 40s when it came out. This is not about age. They must have slept on it for a long time.
Nobody expects an engineer to be a git expert, but if a senior software engineer has heard of git only yesterday or don't have a vague concept of how DVCSs like hg or git work (DAG of commits), then something has gone very wrong.
Maybe there are use cases where SVN is superior (I can't come up with any but they may exist), and maybe engineers in that industry really are so specialized that they never get around to working on anything else!
But maybe it's because nobody else is willing to hire them.
