I don't understand aztecs

Hi guys, I am bad at the game, Elo around 1000.

Sometimes I manage to destroy an enemy TC's early, by FBing early, sending 22 holcan soldiers at minute 6/7, and he gives up and everything is alright

Else some other times my allies will carry the game and everything will be alright

But as soon as enemy can make cannons or stronger units I feel weak, hopeless, lost... feels like my only chance is to go Age 5, visit their economy with 100 upgraded jaguars knights and massacre villages, plantations and expect them to give up and my allies to defend well... like I don't understand much about aztec units, like difference between eagle and jaguar knights, and I would like some help about it please 😊
