It's not about what rights Administrators can promote and demote. It's about the rights that are extended to the group. Discussion Moderators automatically have Chat Moderator rights. So it is useless to mention them individually.

On top of that, Administrators do have all the rights that Content Moderators have. They just can't grant and revoke them. That's a difference.

I think you are just a bit confused. Because the sentence in the help page clearly says "all the privileges", not "all the rights they can grant and revoke".
