Iroh's point could have just been predicated on his knowledge that Zuko was Ozai's son to begin with, but even if Zuko weren't Ozai's son, he could still be destined to fulfill the duties of the Fire Lord's heir.

I still agree with you that Zuko is Ozai's child, for two reasons:

Firstly, Zuko possesses the same physical traits as his sister and father, who both have black hair and almond eyes, of which the latter requires a recessive gene to manifest itself, meaning that both the mother and father would have to carry said trait in order to pass it on to their child. Of course, if Ikem also had almond eyes, then you could rule this out. Or perhaps almond eyes aren't based on recessive genes; I don't really know.

The second reason is that ATLA was by and large a children's show. It would strike me that depicting a character to have committed adultery of any kind on a children's show would be rather crass and unwarranted, as far as plot revelations go. Of course, I suppose this wouldn't be a strict rule against the possibility of Zuko being Ozai's son, but it's a thought, nonetheless.

The only thing that would suggest that Zuko wasn't Ozai's son could possibly be the fact that Zuko is astonishingly different from Azula, but considering Zuko's close relationship with and Azula's isolation from their mother, this could very well be caused by their nurture.
