Larger dog breed live less years than smaller ones - in general
Koi are bred and selected for the potential of their future appearance and are not selected on the basis of how long they live
While many people live past 100, I personally dont expect to live to that ripe old age. Depending upon what country you live in you will find that the average age is around 70-75 years or so. I hope I will live to 70.
While many koi keepers might report they have had or do have koi that live to around 20 years, I do not expect all koi in general to live that long. I expect that the average is much less.
These comments are not science.
