AI Detection on Personal Statement

I've just finished my personal statement and ready to submit but decided to put it in an AI detector just by chance to see whether I write AI like and it came up with around like 21% AI detection? I'm not sure how to feel about this considering I genuinely wrote it all myself with a week in the making and I don't see how I could write a better version in the time I have left (Internal Deadline of 30th Oct). Is this a major problem?

Running your PS through ANY third-party website is a very silly thing to do.

These sort of websites 'harvest' material, and it gets republished/reused it all over the place.
The chances of your PS now being picked up by the UCAS plagiarism checker is now very high.

Please, please don't do this folks!

The ones I've used state they don't store data in any public or private databases.

Is there any validity behind this? The ones I've used state they don't store data in any public or private databases.

Is this true??? I put my PS into a couple AI detectors just to see if my writing is similar to AI... I didn't know this!!!!! I'm really anxious now, will I need to rewrite /rephrase my statement now??
