It seem like a lot of languages can achieve it somewhat, but only some truly have it. I don’t think Spanish has it.
Edit: Read further into the wiki article:
“It is, of course, possible in any language to express the idea of clusivity semantically, and many languages provide common forms that clarify the ambiguity of their first person pronoun (English "the rest of us", Italian noialtri). A language with a true clusivity distinction, however, does not provide a first-person plural with indefinite clusivity in which the clusivity of the pronoun is ambiguous; rather, speakers are forced to specify by the choice of pronoun or inflection, whether they are including the addressee or not. That rules out most European languages, for example.”
