The mapping from username to UID is variable.  Two different Debian
systems may map the same username differently, depending on which packages
were installed in which order.

But you have been asking about changing a user name, because you don't
like the (length of the) names Debian maintainers have chosen.  This is
not going to work the way you want.  Those user names are hard-coded
in many places, from the *.postinst scripts that (re)create the users,
to the systemd unit files that launch services as those users, etc.
