Does anyone know the Blastoise and Volcarona drop chances in the ongoing Blastoise event?

Question

I still haven't gotten any Blastoises in this event, even though I already have 4 event Volcaronas and I got 5 Venusaurs in the last event.

Seems inconsistent

12.66% according to https://ptcgp.raenonx.cc/en/pack/AP001_0030_00_000
Is this enough for an answer?

That site's a wiki, right? I guess we'll just have to trust it until we find conflicting information.

Those odds seem consistent enough with other sites for it to be true.

I just remembered, doesn't the game say it's more likely to drop rarer cards if you battle the more difficult decks? Is that true?
