Extra Line vs 6 atk

It's referred to as gambler's fallacy and I dont' get why people don't understand it's not real -_-

eh.. I watched him scroll a craven 9/9 with 50s using his method; I became pretty (naively, i guess) convinced after seeing it :/ . I do realize it really is all luck/chance but idk there are more than a few ppl that swear by junk scrolling and have their own theories on it and/or results to back them up. I lost faith in it though after experiencing that fail, took me like 75 helm defense 60% scrolls before I finally failed 3 consecutively and then the chaos failed LOL
