I fail to see your logic. Could you expand on the math?
Initial draw is 10 cards of 25 (we'll assume, because higher is worse). if 3 of those cards are X,your chance of draw at least 1 of X is 4/5 (80%). Put another way, you chance of Not drawing any X is 1/5 (or 20%), at only 2 copies of X in the deck you Chance of not drawing any jumps to >1/3 (35%). doesn't sound like much that 15% difference right? but it's actually a 75% increase of your failure to draw rate (35/20) for that specific card X. This means that initial hand is much less predictable, and will require more mulligans to fix (reducing their ability to sear for tech cards) and provide less reliability over the course of multiple game.
Higher end Ranked/Ladder decks rely on repeatability of starting hands to allow them to exceed the measly 12pt bronze average on every play in R3.... usually at 14-20+ (averaging higher) per card played in R3. a single 25pt play doesn't help them when it lowers the repeatability of their deck. unless those decks get an exceptionally bad draw (it can still happen) they will outpace any Ciri deck more often than not, even without card advantage. they can afford to lose a game here and there (facing the same opponent) because on average of all games they come out ahead.
If you're curious about odds for different card combinations, there's a draw odds calculator attached to the link in my signature below, but it's worth mentioning that odds calculations, especially where mulligans are concerned, are best case for a single combination. For a full deck they are much more complex (and lower), but it's educational as to basic reliability.
