If a compound is amphoteric, is it also amphiprotic?

"Not all amphoteric substances are amphiprotic. Although an amphiprotic species must be amphoteric, the converse is not true. For example, the metal oxide ZnO contains no hydrogen and cannot donate a proton. Instead, it is a Lewis acid whose Zn atom accepts an electron pair from the base OH−." I found this online, but I'm not really sure myself.

If a compound is a amphoteric, then for the most part it is also amphiprotic.
