The internet gaslighted me into believing Goku's childhood was a small part of the manga

I am currently rereading Dragon Ball for the first time in like 15 years and I didn't expect Goku's childhood to take up more than 150 chapters cause I rarely see people talk about this part online. I know the whole DB/DBZ distinction made by the anime (and by certain editions of the manga, I believe) influenced the way people perceive the manga but considering how highly praised it is, I find it wild that so many fans act like ONE THIRD of it is irrelevant or basically doesn't exist.
