Welcome to the community!

From what i could tell from your file, if you want to make a render from inside the cube you have to flip your normals since you're looking at the backside.

The perspective from the outside looks fine:

From your Physical camera i got the same result as your screenshot, so i added a "normal" modifier to flip the normals and changed the environment light to a HDR to quickly add some more light to the scene. (the daylight system was too dark and i didn't want to figure out how to change it.):

but now one more problem when I add daylight, for some reason the light falls not inside of the cube, but the cube shines itself, why is this happening?

@Anonymous, To be honest, i'm not really sure what's going on as i don't use the scanline renderer myself. (i use Arnold)

But here's what i've figured out with your scene:

There seems to be a limitation on what Activeshade shows with Scanline, it's different from doing a production render.

You had an unnecessary normal flip on your skylight, but more importantly the skylight wasn't casting shadows.

With that changed it looked like this:

Hope you can get on from here and that this helps.

Oh, and in case you're wondering why you don't see your "window" in the production render....

that's because there is no background, it's looking out into blackness.

No idea which tutorial you're talking about, maybe it was a tutorial that was using mentalray or iray as the render engine....
Lighting can be very dependent on which render engine you use, that's why Arnold even has it's own light object.

For myself, i've found using a HDR image as a scene environment is a really nice and easy way to get your scene lighted.
It won't work for all occasions ofcourse, but it saves a lot of work.

Hope you can figure it out from here, good luck with your learning!
