I dont know why the rig wont behave like normal it like the objects aren't parented to each other or something, I would really appreciate the help as I really want to do this tutorial, thanks.
You need enter to pose mode to do that

select the armeture and pres ctrl+tab
or you can select and change object mode to pose mode when armeture selected
