This was true in the past. Now wifi off is not really off. There is an obscure setting in location where you can disable it. Of course Google does its usual, making it inconvenient. When you enable that setting wifi location is completely disabled and many apps which use finer location will trigger a popup to enable it back in order to get a better location. They do this with any setting that benefits them. For example if you don't allow Google to store your historical location Maps won't remember any locations searched. As if it was impossible to maps store that details locally sigh.
