Goku VS Power Stone Fully Prepped Thanos 1v1

My wife and I (26) are watching Dragon Ball for the first time. She has seen Z so she’s been catching me up how powerful Goku can be and will become, so I just wanted to compare it to something I can fully relate to. I have never watched anime, unless you count Pokemon and YuGiOh.

The rules are:

They are both fighting in a white void space with a never ending floor and no walls. Their only goal is to fight until only one is left standing.

Thanos is at his peak strength and absolute best physique.

Forgive my ignorance but i am here to ask if Goku would beat this Thanos in this state.

Obviously this Goku is a kid, but i know he grows up and gets stronger. But who would win?
