Let’s say we have lemmy instances A, B, C.
alice from A makes a post “Hello, world” to B. What happens? How is it processed on servers A, B, C and how do users from A, B, C receive her post?

All users from all instances get the post from their home instance.

They don’t duplicate the database in a technical sense, but when things go right, they each have a copy of the same post and comment text, and the same votes.

Correct. Each server that shows the post to its users stores a copy of the post. It does not necessarily store attached media (IIRC Mastodon usually does and Lemmy usually hotlinks media).
Ur home instance only has a database of posts that are on a community that at least 1 user has subscribed to.
