Not necessarily. For FICO scoring purposes, you may carry a balance and still never pay a dime in interest: FICO considers your balance at the end your cycle, not the balance after your due date.

For example, if I have a balance of $800 when my statement was generated, my bank is going to report that $800 to the credit bureaus and FICO will calculate my credit score accordingly. So, for this cycle at least, it doesn't matter that I pay in full before my due date (thus avoiding any interest expense), my credit report will show an $800 balance on my account. This is why it's more likely to experience big month-to-month jumps in your credit score when you have fewer accounts/lower credit lines.

I do agree with you, I think that not carrying a balance doesn't have any negative impact on your credit score.

I think there may have been some confusion on my part. When I hear "carrying a balance" I think "not paying the bill in full each month". From what you just wrote I don't think you're talking about what I imagined. If that's the case then my apologies. I just meant that you shouldn't carry a balance over each billing cycle (which would accrue some interest) which is advice that I've seen people give before.
