What are the real random events in real life?

In fact, according to the normal situation, the irregular development of our life can also be said to be random in time. For example, the occurrence of a natural disaster, from the accumulation of a quantitative change to the occurrence of a qualitative change, may or may not happen at any time. Some people may work under such risks all day, and there is no problem. As a result, someone came to that place for the first time, perhaps only once in his life. As a result, geological disasters, such as falling rocks, have caused people's deaths, so this kind of thing is completely unexplained and unpredictable. After all, with the passage of time, the development of anything in a small place is irregular. Whether you go to a place or not, the result may be completely different. We don't know what will happen to those people who are called unlucky if they don't go to those places at that time, and what will happen to their subsequent development?
