Forum:9 Card Zones/Spaces!? O.o

How many Zones/Spaces are there?? aren't there only 7 (technically 6) or

1. Field 2. Monster 3. Grave 4. Extra 5. Spell/Trap 6. Deck 7. Removed

But according to this we have 9

"Conceptually, there is a ninth space called the Banished Zone. However, it is never represented on Official Playmats, since it is not considered "in play"."

Is that just type?? or is there really more Zones/Space!?

P.S. I'm new so sorry if this gets posted in the wrong section or something
