It stores structured logs for each of these entries, see "journalctl
-o verbose", i.e. a *lot* more data than you see in the simple output.

It also maintains an index for field, so that "systemctl status" can
reasonably quickly show only only the data for a specific unit. and so
on.

Which systemd version are you using?

In v252 many of the 64bit fields of the original journal format were
optionally reduced to 32bit, which makes the format a lot smaller.
