Yea, but my question is why does this actually matter. How old your coworkers are is their private information that they can share with you if they wish. At my current company most of the more senior employees are millenials but we do have some Gen Xers that have faced open age discrimination at other jobs and, well, it doesn’t fucking matter as long as you can do the job. Women, especially, tend to get a lot of shit if they’re older and don’t have children or, God forbid, aren’t married - so I can absolutely understand why you’d want to dodge that judgment.

You aren’t entitled to any private information about your coworkers, and that’s a good thing. I am quite confused why this is important because it’s not relevant to the extremely limited relationship you’re forming as coworkers.
