The title is not misleading. You missed the next sentence in the quote from John Carmack:
"So it looks like it’s parallel growth rather than one stealing from the other."
My interpretation is that there is a massive market for convenient casual games that has been neglected for a long time. That market is exploding and represents huge revenue opportunities, but because it targets an entirely different customer base, it is not hurting sales in the serious gaming market.
