1 in 5 on lucky cards is a damn lie too. I had it on like nine cards in my deck, played them at least three dozen times over the course of four antes after I started counting, not once did the +20 proc. .03% chance. .03%. Call me a walking debacle, god only knows why I play games of chance.
It because it's random and not pseudo random. Video games sometimes switch to pseudo random because otherwise things like this happens. Dota 2 had a character with an automatic counter attack which had a 30% (can't really remember) chance to proc. They had to change it to pseudo random because there were lucky/unlucky people getting 0 counters or 100% counters
This is also true because truly random number generation on computers doesn't really exist.

Numberphile has a couple neat videos on randomness, here's one
I counted and it took no less than 15 tries before it ever worked for me. Ever since then then my rates have improved but I'm still highly skeptical of the "1 in 4" written on the card.
I mean.. that's a pretty weird take. Most games have some sort of RNG - whether it be in the background or visibility listed probabilities. That doesn't mean they're promoting gambling.
The outrage over the 18+ rating was partially over other games with actual gambling (monetized loot boxes) are somehow PG / PG-13.
Meanwhile, this game with no in-game purchases and is only thematically about "Poker" is 18+ because it's "promoting gambling".. If the game had an artwork swap they'd see it as a typical deck building rougelite and rate it the same as Slay the Spire.
