  I’m sure most people have more (topological) holes than one

  Both nostrils, for example

    The nostrils are connected to the throat through the sinuses as are the ear canals. Topologically making them all part of the same mouth-anus throughole.

      Not true, topolgically the route

      left nostril -> sinus -> right nostril

      is another hole. So is

      any nostril -> sinus -> mouth.

      ears have the eardrum, so they don’t count.

      For the more formal definitions of topological holes, look up Betti numbers. What we’re currently talking about is the Betti number b_1. For humans, that is at least 3 (but I’m sure I’m missing many more holes). Unless you’re missing the entire septum.
