In a normal 52-card "Poker" deck, there is one "7 of Clubs" card. In fact, there's only one of every type except the Joker, and there are generally two Joker cards. Of course, in Pinochle deck, there aren't any sevens at all.
There is only one of each individual card in a deck. While there are 13 cards of the heart suit, and 4 cards that have a value of seven out of the entire deck, only ONE card is a seven of hearts.

There are 4 9s in a deck of 52 (one of each suit: clubs, diamond, spade and hearts)
In a standard deck of 52 playing cards, there are 4 sevens (one from each suit: hearts, diamonds, clubs, and spades). Therefore, the odds of drawing a 7 from a full deck are 4 out of 52, which simplifies to 1 out of 13, or approximately 7.69%.
