Termux first needs the phone to be rooted to properly interact with anything outside of its $HOME, including Android’s user’s internal storage and SD card
this is false, termux does not need root for most things including accessing internal storage (/sdcard)
Termux is a Linux distro heavily adapted to work as an Android program, but that makes commands familiar; if you used Debian, Ubuntu, Mint, etc., commands follow the same structure as apt’s, but using pkg instead
this is also not true, it’s not a linux distro, it’s just *nixy tools natively compiled for android. thus for example it uses android native libc. apt command also still works on termux, as pkg is a wrapper around apt.
About (not) being a Linux distro, reading deeper into it, it sounds a lot like DOSBox, which is also a terminal emulator which can run programs for the system it pretends to be while using the host system’s file system.

Went to double-check both things.
About root, I think I got it confused with two different things at the same time, termux-setup-storage, and the external storage specifically requiring root to work (first paragraph after the data table).

kinda a small nitpick but it’s not really like dosbox, dosbox is a full x86 emulator.
termux is basically a terminal emulator (like xterm, konsole, alacritty) that comes with unixy tools compiled in the native android toolchain.
