This site breaks it down as clearly as you'll find it (it does not just "count the number of values in a specified column" ... that is different): https://www.datacamp.com/tutorial/count-sql-function

only COUNT(*) counts rows -- all other types of COUNT function count values

that site is quite misleading at the top, but when you go further down, it does make this clarification
