You'd lose your bet. In that "shuu" link as an example, most (10-12 or so) are common enough that you might hear them in a typical newscast, with that pronunciation.
What makes things manageable is the combinatorics. E.g. there are dozens of kanji read "shuu", and many dozens more read "kan", but most of them are only read that way when part of a 2-character compound, and only a small subset of the possible "shuukan"s are words, and only a subset of those words are common in spoken conversation.
Even then, it is a very homophone-heavy language. I can think of four "shuukan"s off the top of my head that you might hear from a newsreader; it would only be after those that you'd get into domain-specific words. This is pretty typical.
