Am I just unlucky?

[Churiset]

I'm just starting to loose interest in dynamax adventures, I have the dex completed, shiny charm and everything done 100+ adventures, do you want to know how many shinies i got from that? A SOLID 0 the only shiny i found on sword and shield was a Perrserker on a random route full odds, I've completed sword 2 times, shield 1 completed pokedex on both games and only 1 shiny??????!!!! how, just how can this be, or im the unluckiest pokemon player alive or im being scammed XD

Assumes 3 Pokemon per adventure. (Went past the legendaries at some point, presumably.) Totals 300 Pokemon over 100 adventures. Finds a shiny with a 1% chance with the Shiny Charm. Means a 99% chance of not getting a shiny per Pokemon.

Odds of not getting a shiny in 300 Dynamax Adventure Pokemon: (.99^300) = .04904. As a percentage, 4.9%.

Unlucky? Yes. Astronomically bad? No.
