in cryptographically secure pseudo-random number generators such as the /dev/random and /dev/urandom on Unix machines, it constantly takes up new seeds to prevent anyone known the state of the generator at any one time fully. It usually uses stuff like block ciphers and hashes to take essentially random input like keystrokes, and hardware interrupt timing to continually shuffle the output to keep it as secure as possible for generating keys and stuff for encryption such as using a https connection. For CSPRNGs it is required to pass tests for statistical randomness as you wouldn't want to use a encryption key even for a one time pad that was a very simple number that wasn't random at all.

Don't think you are safe behind cryptography, but the more bits involved, the more secure exponentially... but with super computer that government can use, 1024bits encryptions is pretty safe probably 512bits is enough for the effort needed for what you are hiding, if you don't know how computer encryption works, I invite you to look for basic encryption videos about it. This video is only about RNG in computing... It has nothing to do with RNG in encryptions...

I just realized that since this video is in a series, it's probable that Khan Academy defined "shifts" in an earlier video. I remember watching these last year and believe that this may be the case.
