You never checked that, because the system is too opaque to check.
Another anecdote: I have three credit cards that I use for various things (recurring payments, real-life purchases, online purchases) and I pay them in full every month. I have a very high credit score. The credit card issuers are making plenty of money off of me; they get 4% of everything I buy.
(Why do I use credit cards? One, convenience. Two, it's an abstraction layer over my own money. If someone mistakenly charges my credit card, they've stolen the bank's money, which the bank will really want to get back. If someone mistakenly debits my checking account, well, so much for paying rent this month...)
