But like OP mentioned, as long as you make some deposit and aim for max bet, I do not think your account will be banned though but just in case
As long as you are using the website normally, it's fine and you shouldn't be worried at all. Max betting is not a requirement (of course).
Right anyone can bet any there shouldn't have any restriction for max betting requirement and they will never ban you if you cant fulfil maximum requirement of their betting.
