From the manual,

By default, ps selects all processes with the same effective user ID (euid=EUID) as the current user and associated with the same terminal as the invoker.

For example, if you open a gnome-terminal and give the ps command, it will list all your processes started from that terminal.

ps -e lists all the processes in the system.
