These two girls are both Chinese. They just add flags to push CCP propaganda that they are superior to all of the nations they steal technology from.

The way she does it isn't 100% reliable. CPUs would use the method on the left.

Does it work for any number combination? Does it work with numbers that have different number of digits? E.g. 456x12?

It's useful only for multiplications of 90s, it's basically (a-b)(a-c) so in that case (100-3)(100-6)
They deliberately pick such numbers because that's a propaganda vid

It only works if the difference between 100 and the multiplicands are single digits.

97x94=(100-3)*94=9400+3*(6-100)=9100 + 3*6=9118
