If a blackjack is dealt 1 in every 21 hands, does that mean I can expect a blackjack with a queen of hearts in it 1 in every 336 hands (tens,jacks, queens, kings =16 x 21)?

Also, on wizard of odds I see the probability of getting 2 queen of hearts (6 decks) is .000295. Is that the same as .0295% or 1 in 2950?
