This is clearly not the case in-game, where healers regularly have to wait for queues, and tanks rarely do.

As for opinions, it's not hard to see from experience that yes, tanks get into queues instantly, and healers have to wait a short while, as I play both WHM and PLD. DD's do enough complaining on the forums to make it clear that the queues are worst of all for them. So, yes, this chart is clearly not usable as proof that there's no queue problem. All very tidy empirical data, accumulated through first-hand experience and second-hand reports.
That number is also many months old. It's not really useful to diagnose today's experiences.
