Hello and welcome to the forums.

You need a bootloader: https://wiki.gentoo.org/wiki/Bootloader and configure it: https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Bootloader

I installed yesterday, today I wake up to see that I couldn't boot it, and to my surprise, I had created /mnt/gentoo on my Arch partition, not on the desired Gentoo one, so I guess Arch auto-deleted all /mnt/gentoo files, because the directory was completely empty, idk if it was the guide I followed or smth, but I'm so confused because I even got a screenshot of a fastfetch done alongside Arch (since you can apparently use any OS to install)

If you used /mnt/gentoo as a mountpoint yesterday, and did not mount it today, then yes, it would be empty today, even if your files are intact. What is the output of blkid? On what partition did you create the root filesystem for Gentoo?

The supposed partition was dev/nvme0n1p5, but /mnt/gentoo was in nvme0n1p3, also blkid won't help because I stupidly removed the partitions.

Now after creating partitions again nvme0n1p5 is mounted to /run/media/<user>/<uuid>, why is that like it?

Are you asking about a behavior observed in the Arch Linux you used for the install, or observed in the resulting Gentoo install? /run/media is typically used by desktop environments that are trying to be "helpful."

Gentoo was removed, so it was Arch after creating with gparted, so I will just unmount it because I mounted it again to /mnt/gentoo, but, does it matter where /mnt/gentoo is?

Installing Gentoo again as I speak, this time reading the Handbook.
