Pegasus is not a "zero click software" which does not really mean anything. It's a spyware
If you don't have physical access to an unlocked device you need to exploit a vulnerability to install it. And what a lucky day, Apple has again failed to solve their zero click vulnerability around ImageIO and the sandbox of iMessages. This type of vulnerability has been recurrent for Apple products
I don’t really get what you’re trying to say but I do wonder if maybe an internal apple employee is somehow working with the company that makes Pegasus and that’s why they continue to have exploits.
