Is the variable "randomNumber" inside of the method function necessary?

Can't we just return the random number instead of making that extra step?

You are correct. Returning the value stored in the variable directly would have had the exact same effect.

The main arguable benefit to the technique shown in the video is that it can make the code slightly more readable, since you can look at the variable name and get a quick idea of what type of value it stores.

I personally don't tend to create a variable unless I need to reference the value multiple places, but some people do create variables entirely to make the code slightly more clear, like was shown in this video.
