If someone gets your credit card number and expiry date they can use it for online purchases as these do not require a pin. Sometimes they need the ccv number on the back of the card for online transactions but not always. You only need the pin number for in store machine translations. If they have your car d details they will just keep purchasing untill in gets declined by either you or the bank or the limit of the card. Most of the time they will purchase gift cards then spend that money on what they want ad it’s harder to trace them.
