There was a conversation on the radio about some tiktok video with a woman spouting the revelation that when a forecast says 30% chance of rain, it does not mean that there is a 30% of rain, but that it's a 100% chance of rain, but a 30% chance of rain in YOUR area. The discussion was interesting as the whole YOUR area is open to interpretation.
Quite honestly I never thought of it that way...the 100% chance, but I suppose it makes sense, since it is going to rain somewhere.
