It's a very strange definition. Would you consider domestic chickens "endangered"? Clearly if there are many kept in captivity and bred, there's little chance of them becoming extinct even if there are nearly none in the wild.
There is in fact a difference between domesticated animals and wild animals that are kept as pets.
Do you also find it strange that e.g. various wolves are/have been considered endangered even though dogs exist?
