A pipe has 1 hole, a cup has zero holes. A pipe is equivalent to a disc with a hole in the center since you can flatten it into that, a cup is equivalent to a disc with no hole because it can be flattened into that

*openings

Amazing, we went from how many openings the human body has to an anatomically incorrect human digestive system to a pipe and then to a cup being a disc.

So you mix the words opening and holes as is possible in common language and then proceed to be anal about the term hole in context of topology. While a scholar of topology uses the common word hole to explain the concept of e.g. an annulus or torus to a student it is not a defined term per se.

For the sake of argument I'll accept your incorrect application of the term hole as in a pipe having only one hole. This would still mean it has at least 2 openings. In the context of OP (human digestive system) an entry point (mouth) and an exit (anus).

BTW - you shall henceforth consume liquids only from platters and are required to use the word berry only in the biological correct sense (e.g.: straw-thingy, black-thingy, rasp-thingy, cucumberry, pumpberry, pinemultifruit, etc. pp. - have fun)
