They are. I think you see the entire concept of 'staff' like /ban and /mute and ingame chat staff.
Staff is also builders and parkour builders - they are also 'employees of the network' and do something for CCGN.
It's basically the same, but one staff member (for example, Mod) manages chat, forum, etc., while the other (for example, Builder) has tasks concerning lobbies and stuff.
I could go on - and I'm going to ;) - for example an Admin has whole other things to do than a Mod and a Builder, so do the Owners. Get my point? :p
