I had the same question about “truthy” and why we typed in “wdt” in Wikidata Query in some places and “wd” in others.

Lukas Werkmeister gave this nice succinct explanation during our Wikicite training, that may be useful:

Can somebody please explain (in simple terms) what's the difference between "all" and "truthy" RDF dumps? I've read the explanation available on the wiki [1] but I still don't get it.
If I'm just a user of the data, because I want to retrieve information about a particular item and link items with other graphs... what am I missing/leaving-out by using "truthy" instead of "all"?
A practical example would be appreciated since it will clarify things, I suppose.
