There isn't one.
But most distributions use uid/gid 1000+ as regular users, and if you
always create a user and their matching group (as the adduser and such
tools do by default), then the assigned numbers will always stay in sync
since they are allocated at the same rate.
So it is pretty much just a coincidence.
