No, the recipients of knighthoods are not generally decided by the monarchy: https://en.wikipedia.org/wiki/Honours_Committee https://en.wikipedia.org/wiki/Honours_Committee (Do you think the Queen was enthusiastic about knighting Elton John or Mick Jagger? https://www.cheatsheet.com/entertainment/the-real-reason-queen-elizabeth-ii-refused-to-personally-knight-mick-jagger.html/ https://www.cheatsheet.com/entertainment/the-real-reason-que...) Also, not all jobs come with an associated title. I'm a software engineer, but people don't refer to me as Software Engineer Joe Bloggs. "President" absolutely is used as a title. This is especially clear with former presidents, who retain the title. (E.g. George Bush, who isn't president, is still President Bush.)
