Only the official Cyanide dungeons are used in Matchmaking, with two exceptions. Roi Lorcan's "Dungeon old school 01" sems to have replaced "Rush" (which is no longer used) and "Cross" (or something like that) hasn't been used in a long time, if it ever was.
I'm guessing all of the dungeons in use have an equal chance of appearing, but it's difficult to tell for sure. There's no easy way to collect that data for anyone else than Cyanide.
