It's near the line, I agree, I see your point, but it's just the terminology and no gambling mechanics. You don't set the ante, you just play. They could change the name ante to level and it would be the same. It's not like you look at your stuff and decide how much you're willing to risk. (You could argue skipping blinds is this sort of risk analysis like gambling but that's hardly unique to Balatro.) There is no benefit from stopping earlier because if you lose on ante one or lose on ante seven it's the same outcome. Also, if you choose to restart one ante one or ante seven it's the same outcome. Because it's just a score keeping mechanism. Nothing more.
