Not necessarily, modern having keyboards can operate at upwards of 1khz polling speed. The main difference is, that usb needs polling in the first place, whereas ps/2 is interrupt based.

That essentially means that ps/2 tells the computer “hey a key was just pressed” instantly and usb waits to be asked whether a key was pressed or not. If the latter is done often enough the difference becomes negligible.
