Although credit reporting agencies have a funny way of calculating debt, which is used for your credit score as well. It's just your current balance, even if you pay it off every month and aren't in "debt". It's hard to tell from the report how they are calculating debt, but I bet it is the amount of money on the credit line waiting to be repaid, even if it isn't costing interest.
Plus, if you wait until the statement due date (which is basically a free extension of the loan, so a good idea, as long as you have automated bill pay that will make sure it makes it right under the deadline), this means that number is likely your past statement plus whatever your current purchases are. You don't control when the credit companies look at your balances, and for mine I was surprised that they were basically reporting 2x my normal revolving credit card usage over the month. I use my credit card for everything if possible, since I get 2% cash back on my Fidelity card (which is great, BTW), as well as great fraud protection and the ability to automatically get an electronic record of every transaction.
The real question is how much of the accounts are delinquent. In the linked report (https://www.experianplc.com/media/news/2019/state-of-credit-...) 6.7% of people are 90 days late on their payment.
