Ranked games question?

So yesterday I play a few matches, I won one of them but my rank stayed at 1 and it didn’t even show my rank on my gamercard in the lobby.
How do I join ranked playlists? Are they all ranked? Because I see something in the left hand of the screen that says “unranked” when i’m picking maps. ?

I only see ranked in one playlist which is the Halo Anniversary one.

Halo 2 Anniversary is the only one with a Ranking system visible to players , but all playlist will have there own ranking system in the future. also if you check your service record on waypoint, you can see your rank for other playlist least I was able to.
