More or less correct. A better description might be that POP3 doesn't
even have a concept of the downloaded email, nor does it have a
concept of remote modification. POP3 really just supports
"authenticate", "give me my mail", and "delete what you have".

FYI what you're describing is just one mode of IMAP operation; what's
called "disconnected mode". IMAP also supports "online mode" whereby
there is no client copy at all, and no synchronisation to be done. In
online mode changes are made immediately to the server-side data.

It depends on whether your POP3 client issues a delete command after
the retrieve command.

Anyway, you're right to avoid POP3. It doesn't suit your needs at all.

Nevertheless if there's no particular need to use the gmail servers as
the repository, you could always POP your mail across to another
server that does support IMAP.

It depends why you're using gmail. For the delivery/address, or for
the storage?

You might be better off finding alternative storage. Note that an IMAP
server does not need to be a mail server.
