"If you send in the minimum payment, you will be charged a late fee."
This is an INCORRECT statement, because you will not be charged a late fee just for making the minimum payment. Minimum payments are not a good idea because you will be charged interest on the remaining amount and will have a harder time paying off the balance, but you will not be charged a late fee.
