No, I know what you mean, I've seen this happen with very cheap (or not cheap but just rubbish/spyware) brands/models that quickly filled the system partition over time with bloatware during updates.
Being cheap, the system partition was already tight on purchase, so the bloat/spyware quickly turns it unusable. The cheaper models tend to have inadequate storage to begin with and install bloat/spyware to subsidize them.
I just don't think it's an "Android" thing, most of those can be revitalized by installing a custom ROM without the spyware (but the crappiest brands are probably not even FLOSS-supported).
Honestly it's been a while for me too and I don't even know how to see the actual device partitions instead of just mounts (e.g. I think in this case your / is just a read-only ramdisk so it doesn't really matter what df says... mine is 100% too.)
I don't even know how this works anymore since I think since Android 10 they use some sort of overlay FS for updates?
I tried installing parted on Termux but it refuses to do so and I have no energy to fight it.
I know it's cliché but... have you tried a factory reset?

I will when it starts to annoy me.
Or I may just get a new phone the next time I need to do Android. This one has 12, they're at 15 now. I may need to be on whatever's the latest on a new project, whenever that comes (not soon).

What is your device brand+model?
