There are only two kinds of users on a Unix system: root, and not
root. All users other than root are "normal" users, even if they
exist only to run some service on the system. Using a UID < 500 for
users which run system processes is a convention of Red Hat, which
need not be adhered to, and relying on that convention could
conceivably result in (a relatively small amount of) grief.
Other distributions use 1000 as the UID to start adding "regular"
users... Some Unix platforms (including some older Linux
distributions, IIRC) simply use the next lowest unused UID (i.e. if
the highest UID in use on the system is 56, then a new user added to
the system will have UID 57, unless you specify otherwise).
While it's true that on Red Hat systems, accounts with UIDs < 500 are
set aside for "system" accounts, you should be aware that there's
nothing particularly magical about either the number 500 or the
accounts which use such UIDs. It is simply a convention that such
UIDs are used for accounts which don't have a human user associated
with them.
