Three typos in college supplement essay...

I just realised now that I made three typos in my supplement essay for Wellesley… I proofread it a lot and had three people read it, but no one noticed the typos. Will having three typos in an essay affect my chance for admissions? I’m really worried because Wellesley is my first choice college.

to be more specific, the first mistake is “all I need be” → “all I need to be.” The second one is “board range” → “broad range” and the third one is “pubic relations manager” → “public relations manager.” The third one is so embarrassing
