In a word: No. Only thing that matters is you — your Whole Person Score, to be more specific.
SAs don’t care if you’re coming from a school, town, city or congressional district with multiple appointees. None of that directly impacts your score.
If it ever does/did affect future results, I think the opposite would be true due to the "diversity" factor. There's concern that more outreach is needed to diversify the applicant pool from areas/categories currently not equitably represented.
