Several genealogy books reiterate this fact. After about a thousand years, nearly everone is your descendant or no one is. I believe this has been both proved by simulation and checking genealogic records. Some of the most detailed genealogies in the US are for the 45 Presidents. Most are descended from King John of England. Most are 11th cousins or closer to each other, including Obama via Mom's side.
