It's also a bad statistical method because if there are 300 cities/regions in the world and a storm hits a random one of them most severely each time, on average you will expect to have one city/region every year seeing a 300-year storm even in a static climate.
Not that I think the climate isn't changing, but because if the headlines are obviously p-hacking all the time you get all climate change reporting eventually called fake news even when it isn't.
I think these terms state how likely some event is for some climate, which is useful for people who don't live in that climate. It isn't so much used for real statistic.
