I can say that everyone bought scratch ticket out of gut feeling.
ain't no way people feeling so unlucky gonna just go buying some scratch ticket randomly, so the chance of people trying to explain their luck by just simply having gut feeling is higher than you probably expected.

since it's basically just game of luck, i'm pretty sure the winner wins because it's pure luck, so I think anyone thinking it's due to math calculation or something like that, just overthinking it.
the guy got lucky that's all.
