I beat a guy who was using mega fug, primal groudon, primal kyogre,

No, you were just facing a literal kid.

I 1v1 somebody's Arceus grass with my spdef max hp tumblurina (male) as I went for light screen turn one, lived the judgement and he kept going for earth power predicting my A-muk, then he died to moknblast eventually

I 4-0'd someone using Z-geomancy xerneas, mega rayquaza, complete zygarde, and palkia with wooly crab and porygon 2. Am I the chosen one?

No

Was it in AG?
Because literal children play AG with un EV'd legendaries with some of the silliest movesets possible just because they have no idea how competitive pokemon or showdown works. Beating that with UU mons is not hard, I used to sweep mega fug + primal kyogre/groudon + something else in battlespot using a Rotom - Heat, Porygon2, and a Weavile.

I also sweep a team of OU using only a team of Unown. But I'm not gonna provide proof because I'm just that trustworthy. :^)
