Haha, that's the perfect spin on it.
Definitely all cockerels, probably three sex-links and a very handsome boy I don't recognize. In all likelihood the crafty buyers had already scooped up most of the pullets through color- or feather-sexing and you got the short end of the straw. If you want to avoid situations like this in the future, I'd advise buying them sexed from a hatchery.
