Yes exactly, additionally you probably don’t want to host your pi hole for external use (mobile phone or laptop in a different network) for the reason of latency.
The delay that is imposed by visiting your pi hole at home for each DNS request is going to be very unpleasant.
Rather rely on an external dns provider that provides pi hole like funticionality.
But this does not mean that you can’t also host your pihole for internal use. I use it not just for removing ads, but also to allow the access of local domains.
