Yes, every user on linux has to belong to a group. Group is a larger unit than users, obviously; by default when a user is added to the system, a group with the same name is created. This is called a primary group, and user cannot be placed outside of it (although you can change the primary group of the user).

NAME
groups - Displays your group membership
SYNOPSIS
groups [user]
DESCRIPTION
The groups command writes to standard output the groups to which you or the specified user belong. The Tru64 UNIX operating system allows
a user to belong to many different groups at the same time.
Your primary group is specified in the /etc/passwd file. Once you are logged in, you can change your active group with the newgrp shell
command (see sh). When you create a file, its group ID is that of your active group.
Other groups that you belong to are specified in the /etc/group file. If you belong to more than one group, you can access files belonging
to any of those groups without changing your primary group ID. These are called your concurrent groups.
NOTES
The /etc/passwd and /etc/group files must be on the same node.
EXAMPLES
To determine your group membership, enter: groups
The groups to which you belong will be displayed. For example: devel prod
FILES
Contains group information. Contains user information.
