its doesn't even matter about his usage, as Chris says, it sounds like it isn't even the same clubs.
I didn't look but if he has starter gear, then you are talking like .5 dot on forgiveness and about the same maybe a bit more on precision. If he is purposely missing by a lot his circle of deviation is enormous, compared to the people who on youtube probably using g20, or r11s, or maybe even r1, which all have min 4 dots on precision and min3 dots on forgiveness, with r1 having more on both. If someone one with one of those misses badly the circle for deviation is far less, you can't even try and compare the two
I didn't check vids or OP gear, cuz it really isn't that important, just know it is impossible to try and compare the two
