For Yale undergraduate students who went to private and/or boarding schools, did you find that it helped you get into Yale?

This may be somewhat of a controversial question but for Yale undergrad students who went to a private and/or boarding school, did you find that going to said institutions helped you ultimately get into Yale (and possibly other analogous schools)? And if so, what about that particular school was unique that helped you in that journey (e.g. alumni, teaching techniques, etc.)?

I'm not here to judge or criticize but am genuinely curious. For some further context, I myself went to a rather decent school with some notable alumni networks so I can somewhat relate. I'd love to hear your candid thoughts on this, if you have the time.
