I assume you're using bash as your shell. Bash doesn't set a GID variable. The list of Bash variables mentions EUID and UID, but not GID.
Zsh, on the other hand, does set GID:
$ bash -c 'echo $GID'
$ zsh -c 'echo $GID'

@Coreyecho $GIDin my terminal would run it in zsh, since I use zsh as my shell. In your terminal, it might be run in bash. I usebash -c ...to run the command specifically in bash.
