I like watching science videos on YouTube and I have a very basic understanding of electronics. But I never seem to get the “negative voltage” thing.
Why is it used and how does it differ from normal voltage.

it doesn’t differ, the reference is just different.
e.g. you have a set of stairs with 10 steps, it is both 10 steps up(+) and 10 steps down(-), it depends on whether you are standing at the top or the bottom of the stairs
