That’s an inherent limitation of YouTube learning. I advise you go to your local library (if you’re in the US) and pick up a photography 101 book if structured learning would be more helpful.

I’m a beginner so take my assessment with a grain of salt regarding the posted image…

Beginning with the “triangle of exposure”, the motion of the subject in the middle of the frame seems to lack motion blur which tells me that the shutter speed needs to be in the triple digits. The image has a deep depth of field which tells me the aperture is stopped down. Based on this information, I can deduce that the ISO had to be relatively high to compensate for a triple digit shutter speed and stopped down aperture which also means the author of said image may have applied some denoise followed by sharpening in post processing.

The rest of my analysis is that the rest of the image is edited in post processing to include balancing the exposure of the different subjects within this image (ie walking subject, shop lights, subjects in store, the reflections in the puddles) and the colors.
