[45 Card Shuffler] Doesnt Random mean different results?

My code reads the integer, and if it's greater than 52, then take the modulus of 52. Use that to generate a number to it from zero. Use that number as the index of the swap. Unless I understood it wrong (probably) wouldn't the random value mean a different shuffle every time?

Nevermind. The question emphasized using Random values so I got confused...
