Tty consoles and their peculiarities...if any

Hello,

While preparing an upgrade, I read the relevant chapter in the Debian Wiki. Here's what it says:

Obtain a text shell.

On desktop machines, switch to console tty via Ctrl+Alt+F3 (the upgrade should be done on a text console, because your desktop environment could freeze during post-install/service restarts,
leaving the system in a broken state.)

Up to now, I've always used the terminal (tty7) to perform an upgrade, but from now on, I'll follow the Debian Wiki's recommendation. Nevertheless, I don't understand this: why tty3, why not tty1? or tty2...6?
Is there a particular use for each one? If so, where can I find information on these 6 consoles and their uses?
