It's not surprising imo. If you don't go significantly out of your way to be in spaces where you might bump in to someone you'd date, it's unlikely to happen. "designated dating spaces" like apps and bars have largely been failures so people are returning to tradition of trying to bump in to people semi organically.

I'm a gay guy so the situation is a little different/more level but I put a lot of effort in searching out local events, clubs, hobbies and attending a whole bunch of things I don't actually care that much about, just in an effort to be more visible and meet new people. Because getting to know someone first without jumping directly in to being serious like you get in dating apps is way better. You wouldn't consider it weird to join say a hiking club to make friends as the primary goal over just the hiking.
