In his video, he wants the random number from 1 to 6 and he uses math.floor(math.random() * 6) + 1. So if he doesn't plus 1 at the end, there isn't a chance of getting number 6 from that method. You can try it by yourself again. Good luck.

math.random() * 10 generates a random number in between 0-9 (9.9999999 10 not inclusive)
math.floor rounds the random number downwards
and since we want a number in between 1-10 we add +1 in order to round down in between 1.something and 10.someting

The range before adding one is [0,5] (inclusive) and after adding 1 it becomes [1,6] (inclusive). Any number you add this way is going to increase the minimum and maximum possible values by that number.
