If I log in to a site from my machine, and set up a passkey, but then log into that site from another machine, it'll just see no passkey present and ask for my password, yes?
A passkey is a local password on a device that could be shared through all the password manager gymnastics, but its not required as I understand it.

Yes, that's right. It might also make sense to generate multiple passkeys for an account. For example, a separate one for logging in from Apple devices.
I think there are passkeys that can be migrated/synced between devices, and device-bound passkeys that can't. I do save passkeys on my password manager and use them across devices, but I am pretty sure I have had passkeys that I could only use from a specific device. Not sure though, it feels a bit confusing.
