Maybe....
your latency on your network might be 0.6ms, but for most practical use-cases, it will be orders of magnitude more. Partly due to the interference and half duplex nature of wifi, but also because of CSMA/CA (carrier sense multi access / collision avoidance) algorithm, which listens before transmitting to ensure the channel is clear, and waits when it's busy until it's clear before transmitting. The actual transit time for each frame is very short, but getting to the point where you can actually transmit is the main challenge for wifi.
Propegation time for a 1500 byte frame on gigabit Ethernet is approximately 12 µs, or 12 microseconds, aka 0.012 ms. So the argument is kind of squished here. Given that you have a dedicated channel to the switch (and not needing a carrier sense, collision avoidance of detection algorithm with ethernet) the frame can be immediately sent, so the total transit time from a computer connected by ethernet to a router or switch is orders of magnitude faster.
Here's the thing - it won't in real life.
