Excellent piece of mischief but it certainly will NOT help a novice understand series or parallel circuits. That said it's a good brain teaser,
It is almost comical how many people run to "video editing!!" because "you can't have a complete circuit if one of the switches is open!!" Well duh, that's the trick.
Neither the battery or the switches are what they appear to be. The battery is likely not really a 9V. Instead it could have been hacked up to contain something like a SMT 555 to generate a small amount of AC.
As for the switches, take a look at this rocker switch data sheet. You can have switches built to work almost any way you want. It wouldn't take much to add a small coil (or other component) inside while being an "on-on" switch marked as an "on off"...

The author of the video states in the comments (in polish) that the battery is a regular 9v battery. However this doesn't rule out the resistor being an open and the switches having their own internal source.
Obviously the switches are not normal switches. The question is how are they modified to individually address each LED with even brightness and no noticeable effect on the other LEDs.
If its not a video edit than those are some sweet leds, never seen a fully addresable led all in one
Here's a fairly implausible way to do it: each "switch" contains an RF transmitter, each "LED" contains an RF receiver, the wires just supply power. Or maybe IR?
The series one baffles me the most, and makes me think its a video edit, unless it some sort of onewire enabled devices? I've never heard of a onewire led, especially ones that are wired in series just blows my mind
I kinda want to believe it not an edit cuz that would reall be a cool trick to know
Lmao I wonder why the circuit is shown on a "greenscreen" XD
