I won't put $100k against this, but I'll put $10k against it, because "the truth" is worth it. I'll pool $10k into a $100k stake behind a debate team that can debate this (and validate that this is actually refutable). This is valid until 2021-03-01.
The comment you've replied to is a counterexample to this claim.
For example, the meaning of the word "ambiguous" is not ambiguous. If somebody were to ask what the word meant because they did not know the definition, it wouldn't make the word's meaning ambiguous. It would make that person uninformed.
