Wifi's latency has a high dispersion. I've seen absolutely terrible wifi latency, and latency that is under 1ms. wifi degrades gracefully, which makes it really tough to work with.

But pretty much all serious gamers use an ethernet connection because wifi is a pain in the ass. In fact, the first thing a support representative for any game will tell you when complaining about excessive lag is to try a wired connection.
