That is correct - it can only do that. procmail is a mail delivery

That's right, but that is not all. Exim is a complete mail transfer
agent (MTA), so it can also receive mail. What's more, it is also a
MDA. You don't need procmail with Exim, but you can use it.
There's always more than one way to do it. ;)

It isn't necessarily.

The latter only if you need to download mail that was received by an
MTA elsewhere to your host. Exim is fully capable to receive mail by
itself - if that mail is sent to the host Exim is running on.
