I don’t think he’s saying that a 0 rated person is likelier to get a draw against someone rated 2200, compared to someone rated 2200 drawing a 2500 rated player.
That makes absolute sense. I can compare it to when I started learning Russian, and went from zero to reasonably competent conversational in three years. However, it took me another seven to get to somewhere near native level. From a practical point of view, that last seven years makes about 10% difference, yet it was around 70% of the work.
