*% means Turnitin's AI score for your file is somewhere between 1% and 19%. It hides the exact number because low scores are more likely to be wrong. It doesn't mean 0%.

Turnitin only shows the actual number when it's 0% or 20% and above. Anything in between becomes *%, with a note that low scores are less reliable. Your faculty sees the same thing.
Usually no, most colleges treat *% as nothing serious. But some faculty also run reports through other tools like GPTZero, and those can give a very different number for the same file.
If you used AI for any part, read those sections again and make them about your actual work. A checker that marks single lines helps here, because even a low overall score can hide a few paragraphs that read as AI.
The AI score is between 1% and 19%. Turnitin doesn't show the exact number in that range.
No, it means low but not zero.
