Do programs in /bin or /usr/bin should be invoked from a shell?

I started my Chrome and Firefox from search bar and find they were also opened from a terminal

user@host:~$ pstree -aps 5221 | head -10

systemd,1 splash

  `-gdm3,1027

      `-gdm-session-wor,2418

          `-gdm-x-session,2529 --run-script env GNOME_SHELL_SESSION_MODE=ubuntu /usr/bin/gnome-session --session=ubuntu

              `-gnome-session-b,2545 --session=ubuntu

                  `-gnome-shell,2741

                      `-chrome,5221    

                          |-cat,5227

                          |-cat,5228

                          |-chrome,5232

Chrome was invoked from a GUI utility called gnome-shell.

Does any installed software should be run from a form of terminal?

Additionally, I find the terminal I am working is not named tty but

user@host:~$ tty

/dev/pts/0

and can't communicate with tty2

 user@host:~$ echo "very strange long text" > /dev/tty2

 user@host:~$ grep -r  'very strange long text' /   2>/dev/null

does not return valuable message, the text to tty2 lost.
