Well, here are a few idiomatic expressions that, while they make perfect sense, don’t mean what they originally meant.
“Have an axe to grind” originally meant, as near as I can tell, trying to flatter or curry favor because of an ulterior motive.
“To each his own” originally was a shortened version of “To each his own is beautiful”, in essence restating the choice-supportive bias, meaning the tendency of people to convince themselves that what they have is great.
And “Murphy’s law”, oft-quoted as “Anything that can go wrong will go wrong” was, to the best of my knowledge, originally phrased as “If there’s more than one way to do something, and one of them will result in catastrophe, someone will eventually do it that way”; hence more a statement about people doing things without thinking them through, rather than mere chance.
