What is the main difference between the black swan incident and the gray rhinoceros incident?

? There are three differences between grey rhinoceros and black swan:

First, the black swan is a metaphor for small probability and big impact events, while the grey rhinoceros is a metaphor for large probability and big impact potential crises.

Second, the black swan occurred directly in a short time, while the gray rhinoceros had a certain degree of external performance, and it broke out only after accumulation.

Third, the loss of the black swan is limited, while the grey rhinoceros will cause us huge short-term losses.
