Users must be in a certain group to use the sudo command, typically either the wheel or sudo group.
This is too absolute: sudo access does not require membership in a special group. The sudo policy can authorize individual users directly, or groups, via the sudoers policy.
Full reasoning
Official sudo documentation says sudo lets administrators delegate authority to certain users (or groups of users), not only members of a special group. The sudoers manual likewise says the /etc/sudoers policy is made of user specifications and that User_List entries may be individual user names as well as %group entries.
So while many Linux distributions commonly use a sudo or wheel group as a convenience, it is incorrect to say users must be in such a group to use sudo. A user can be granted sudo privileges directly in sudoers without belonging to either group.
