I'm just starting out with electronics, this should explain why my "schematic" is so readable.
I'll attach it and explain further.
I know how to create a simple circuit with the main slide switch and either of the LEDs, but I honestly have no idea on how would I create 3 parts that are powered by one source but aren't connected "in one line" (Is that called a linear circuit?).
My second problem, that I have not illustrated in my schematic, is – how, if it's possible at all, could I create the potentiometer control the 7 segment displays so they display random numbers (or just light up random parts of the screen, really).
The display should change only when potentiometer is turned.
I hope that I make some sense and you can give me some tips on where to start.
Thanks!

The circuit that you show in your sketch has three branches connected in parallel - something like this (although I only show two branches):
simulate this circuit – Schematic created using CircuitLab
In this circuit, SW1 is the main power switch - it turns everthing off.
SW2 will turn D1 off and on, if SW1 is on.
SW3 turns D2 and D3 off or on, if SW1 is on.
The resistors R1, R2, and R3 limit the current through the LEDs to about 13 mA.
As Respawned Fluff indicates, some more complex circuitry is required to drive the 7-segment displays.
