That's just over one tenth of a percent of YouTube's over a billion monthly active users. Obviously Red is only available in a limited market and requires more time to be available worldwide but I assure that Google is not happy with mere million or two million payers. That generates under 200 million of revenue which is peanuts to Google.
Seems that YouTube needs to be investing a lot more (in exclusive content) to get the type of traction it needs to compete against the likes of Netflix which is closing in on 100 million subscribers.
