URGENT PLEASE Issue with Personal Statement and AI

Ive written my personal statement myself and i put it into an AI checker where it gave me 0% that AI wrote it but if i do a select few paragraphs at a time or a singular paragraph, i get 100%, 83% and 73% and other various figures. What should I do?

Also is it true that when you submit your personal statement, it gets reviewed by 3 recruiter/the people that review your personal statement at the university you apply to where only 1 of them is knowledgable in the specific subject you apply to and in order to remove biased opinions, the other 2 are reviewers outside of your subject. Is this True?

You don't need to do anything. You wrote the statement yourself so it's irrelevant and you've worried yoursel uncessarily by using the checker. Ignore it.
No, this is not true. Every course has its own selection process. Some might use this method, but I suspect for the vast majority your PS will only be looked at by one person who may or may not have an academic background in the subject area.

I appreciate your quick response. I have written it myself but if it does get flagged for AI since their detection software is more advanced, they wouldnt care about if i wrote it myself or not if the AI percentage is high and scrap the personal statement anyway no?
