The likes of TikTok would disprove this guess, but given the age profile, your theory may still hold true if age-range-bound.
Mastodon/Fediverse instances feel like a nice big random AOL chat room, or Reddit threads in the Twitter format. It won't connect you to your current social groups (except the very few who are like 'Yea I'm on that. Here, follow me), but rather help you exchange ideas with a bunch of randos. Which is something that was pretty damn cool about the early Internet really.
