From what i've seen game wise you can access all the maps in all the game modes. Seeing as when you played ranked matches it's completely random and you have no real choice over which maps you get you will just need to play until it unlocks.
If you go through the private match setup you will see that no matter which game mode you setup you can pick any of the maps which are listed.
