Is your career ratio relevant for matchmaking?

Is my personal career rating relevant for the matchmaking?

If I have a low score, do I get placed into a game with other players with low scores (and same for high score), or are people matched together regardless of their personal score?

Edit:
After some research i found some speculation threads where some people think there is indeed a career based matchmaking because of longer waiting times for high career points players. But this only pure speculation without facts, it would be nice if somebody knows a reliable statement of developers or fact based information.
