Warning: Gach box at your own risk.

And a casino does not divulge all odds. If they did, I'd like to know what my odds are of winning with any given hand when the dealer has an Ace up in blackjack. Yeah, not happening.

It's a closed system, Bayesian logic does give you those odds. You know exactly how many cards there are (52), which ones will beat your hand, which ones you can draw that would make you win, and so forth. It is relatively difficult, but there are people who know those odds. With the Gold Boxes, you have no idea how many items there are, or how likely they are to come out. A lot less certainty there.
