Does the gear count as a model?

I bought a Collector's Trove booster pack, which advertised having 5 models. That said, I only got 4 characters (Thor, Gambit, Iron Man, and The Collector), but my Thor came with a Mjolnir.

I'm mostly curious because the other booster pack that had an item like that I got still had 5 minis. Was that a fluke, or was this the fluke?
