Well what that paragraph means, is a program that itself makes/forces access to the game code to get info/to change parameters that normal players shouldn't have access to.
A clickbot doesn't do that, it's just recorded the clicks of the mouse and repeats them that means it doesn't affect the game code at all and as such doesn't go against the rules.
Yeah it's not nice, but such things are in most games not covered, because there is no possible way for a developer/publisher to prove sth like that if it doesn't affect the game code directly.
