The law of averages does not work in that way... countries and economies work on predictability so anomalous events are almost always bad... things like a bumper crop in agriculture are not really counted here because they don't pop-up suddenly but even so can happen in such a way that unaccounted excess provides no benefit and ends up being wasted.
The only REALLY GOOD unexpected event I can think of recently is that Covid ended up being FAR LESS dangerous than predicted. This was a very good thing even if it was not acting on correctly by the government.
