“Antes” are what Balatro calls its levels. Each level consists of 3 stages, which the game calls “blinds” (small/big/boss).
In poker, you don’t “beat” an ante, it’s part of what you bet. You also don’t “reach” blinds, nor is there such a thing as a “boss blind” in poker. And the word “bet” or any synonym should be pretty conspicuous by its absence in Balatro’s description. There is no gambling without betting/wagering, after all.
So yes, if you’re familiar with poker, that description should make it obvious that the words have different meanings in the game than they do in poker.
The only actual ‘mechanic’ that’s actually the same in Balatro as in poker is what comprises the different hands, and their relative value. And even then, there are also hands in Balatro that don’t exist in poker at all (five of a kind, flush house, etc.).
Also, the simple fact is that there is no reason that any entity promoting their product has to choose any of these platforms over the other–you can just post to all of them, every single one that has enough users to be worth posting to.
