Sure, but this isn't a digital version of a casino game. It's a digital version of a blind box. And there is no rule to say that trading cards or collectible card games need to have equal possibilities of yielding a specific card. That is very much the opposite of how that works. Physical blind box offerings absolutely use different probabilities and different content rarities.
So yeah, if you make up the categorizations, the rules and the mechanics we can be talking about whatever you want, but in the real world that's not even close to how this works in either physical or digital form, which I guess explains the confusion.
For the record, multiple games offer a readout of the possibilities of getting a particular type of thing. I, you may be surprised to know, haven't checked the probabilities being accurate in all of them, but I'm gonna need some specific proof of someone fudging them, because that's a problem of false advertising at that point, forget gambling rules that don't even apply.
Also, 1% is a HUGE drop rate for rare items in loot boxes, both physical and digital. 1% is, as it turns out, 1 in 100. Lots of games, collectibles and other types of blind boxes feature way more than 100 tries at opening a loot box, even for fully unmonetized ones. If anything there's a bit of a cognitive bias there, where people are very bad at instinctively understanding how percentages work, which makes disclosing loot box percentages a bit of a challenge.
Look, I'm not sure what games you play or your understanding of how any of this works but, respectfully, you're misunderstanding it pretty deeply.
