Yup, I don't know how credit cards are in Europe, but, here in America a lot of credit card usage is decided on what rewards the user gets for using it.

Some are better for groceries, air fares, or hotel bookings and pay out in different ways(cash, or an abstract token system that is formulaically tied to redeemable goods and their USD worth.)

This whole system is financed through credit card transaction fees that are applied to the business owner's expenses during the transaction. Note, the customer is not meant to pay for this fee and business that tac this fee onto the customer's bill can have their license taken away by the company that provides in the interface(VISA, MasterCard, etc.). The whole system is really interesting and worth a read on Wikipedia.

That's part of it, but isn't another big piece of it financed by interest payments from people who don't realize that you're supposed to pay off your entire balance every month?

I am not an expert on this topic tbh, but here is a VOX video about the topic more.
