[Avatar: The Last Airbender] What was the point of aang’s journey

The avatar state gives the avatar the skills and knowledge of every previous avatar, so what was the point of aang learning the other 3 elements in such a short time? Did his 1 year of training and and becoming proficient with the other 3 elements really turn the tide of his battle with Ozai where the other 1000s of years of experience didn’t it or would have it been easier to just go after the fire lord the moment he woke up and beat him before Sozin’s comet?

Aang wasn't in the Avatar state for most of that fight. Without the experience and training he'd had over the course of the year, Ozai would have taken him out before he could even enter the Avatar state.

It's also possible that if he had not been a fully-realized Avatar he would not have succeeded in energybending Ozai's chakras.
