Yes, some of us may have a different understanding than what they include in the ToS, as there are often sentences that seem to imply a certain meaning, even though they don't actually mean it.
This is why we need to reach out to the support channel in order to confirm whether our understanding of the ToS is the right one or not. Misunderstanding happens when the reader vaguely understands the written terms and interprets them according to their understanding without verifying whether their understanding is correct. I once make this mistake so I know this kind of misunderstanding exist.
However, once a casino has determined that a user has committed a violation (of any kind), their decision is usually final, especially if the user hasn't provided a valid and reasonable reason. I've rarely seen a user win when deemed to have committed a violation, so the casino ultimately decides.
True that, just like the recent case in my country, the Bingoplus controversy, where the player won Php397 million or $6,688,513.08, and the platform voided the winnings and insisted that it was a system error.
