This depends a lot on your particular situation and equipment. I ran the ping test exactly as shown, with wi-fi and wired, and there is negligible difference in average latency or standard deviation. Even when using ethernet, the PC connects through an Orbi mesh router, two hops away from the base station. A round trip to local IP addresses is between 9-10ms. Switching to wi-fi adds 2-3ms to that.
