There is no "one" card but there is an Ace (which can be used as a one in many card games and also has three letters).

This is interesting

The Chinese invented playing cards in AD 1000 - so herewith some interesting facts and observations about "playing cards":

Did you know that the traditional deck of the playing cards are a strikingly coherent form of a calendar? Very intriguing indeed!

There are 52 weeks in the year and there are 52 playing cards in a deck.

There are 13 weeks in each season and there are 13 cards in each suit.

There are 4 seasons in a year and 4 suits in the deck.

There are 12 months in a year so there are 12 court cards. (Those with faces namely Jack, Queen, King in each suit.)

The red cards represent Day, while black cards represent the Night.

Jacks = 11, Queens = 12, and the Kings = 13, then add up all the sums of 1 + 2 + 3 + ...to 13 = 91.

Multiply this by 4, for the 4 suits, therefore 91 x 4 = 364,

Add 1 that is the Joker and you will arrive at the number 365 being the days in a year?

Is this construct a mere coincidence or the sign of great intelligence?

Of interest is the sum of the letters in all the names of the cards,  e.g., add up the letters in "one, two, three, four, five, six, seven, eight, nine, ten, Jack, Queen, King" = 52!

The Spades indicated ploughing or working.

The Hearts indicated love for the crops.

The Diamonds indicated reaping the wealth.

The Clubs indicated protection and growth.

Also, in some card games 2 Jokers are used - indicating the Leap year.

This mathematical perfection is mind blowing!
