Don't ever believe video guys ;-)

-12 dB (digital audio) = 0dBVU in the analog world. But "au contraire" in
digital audio you want to use all those bits to gain more resolution of your
signal, so from -12 to 0 dB is perfect in the digital world. Where in
analog, from 0 to +6 dB may give some saturation and eventually clipping.

So basically it's all the way around.

BTW, you should try to always record your digital audio as much near
possible the 0 dB to avoid any normalization. The more you leave your file
alone (no dsp) the best result you have.
