Your quote also has already mentioned the reason, so what else could you have wanted form them, that is why we need to understand the reason why we have to understand reading on their terms and conditions and see that we don't violates the rules when gambling, honestly when most people report for situations like this, they are mostly as a result of their violation, because the security system will detect for such and also, the team will take up action by restricting the account form certain features.
Maybe at least, you can try to study first.
Card Counting is not a crime, as long as the count is using our brain and not a machine or cheating device. In US laws or the Gaming Commission, Card Counting is not a crime; they already explained this. Most of Card Counting is not being banned due they count but mostly casino will try to use a reason "We are not welcome you here, and please leave" by using Private properties.
Also, Online Casino is not possible to be card counter. You want to know why? because the decks having 6-8 deck and the deck will be shuffle again atleast after half the deck are usually already out meaning even you count all the card from begining to end. You will not get a good result cause they having so many deck almost 6-8 and the deck is being shulf mostly half of the deck.

Since Stake running in US, they should know these too.These the first time to see these case.
