Look at the key. They go by Rookie, Bronze, Silver, and Gold tier. You may want to look at the "Test" tab. The first page you were looking at is the old matchmaking.

Also, most of the time you'll be put in the correct tier according to your equipment. Once you win too many rounds, it'll bump you up a tier until you lose a couple rounds.
