When Yhwach said that Yamamoto had became weaker over the 1000 yrs he was talking about his bloodlust. Either before that or after that he said that the Gotei 13 of old was nothing other then blood thristy thugs. And that when they found a sense of honor they stopped being a respectable.

Meaning that the old Yamamoto would have killed Yhwach with no honor in it before Yhwach could do much about it.
