thats not always true, the number 2 in japanese is pronounced ni however counting and the singular number can be different when counting different subjects. For instance if you go out to eat and they ask the amount of people, and you reply Ichi or Hitotsu they may have NO idea what you mean and each of those means 1 the correct term when speaking of people would be hitori.
summing up Ichi Hitotsu and Hitori all mean 1 and there are additional phrases for different situations that all mean 1
as far as a game console I am not sure but I know it would not be Ni as it would be counting an object and I'm about 99% sure there's a different term to use.
