My friend told me that macbooks have their RAMs behind the CPU (or something along those lines) and it got me wondering. Does the distance between CPU and memory really make that much difference? 🤔

Like a primer? Sorry, I don’t know anything off the top of my head, but all this stuff is literaly 1st-year computer engineering in college. The basic of ISAs, circuits, low level programming and computer design are all kinda background you need to understand why RAM trace length is so important.
There are definitely college courses you can look up and read for free.
Most “guides” you’d find on Google repeat outdated information; watch out for that. That’s why the Apple “memory on the CPU” thing keeps persisting, as most discussion isn’t even updated to account for CAMM modules.
But ECE focused magazines are good about covering and explaining commercial memory tech:

PC hardware news sites used to be good with this, too. That’s where I learned some of this. But they’ve mostly died out :( And the YouTubers that replaced them are not the same.
