Recommendations for College

I recently had an interview with an alumni from one of the colleges I applied to. Towards the end of the interview, I asked if there was anything I could do if I did get wait listed to the school, he informed me that he was on the Board of Advisers for the college and that he was very impressed with me and my qualifications, and that he would put in a strong recommendation for me. I’m just curious if him being on the Board of Advisers has a large impact on my likelihood of acceptance, if anyone knows. Does this almost ensure my acceptance?
Thanks!
