Diablo 3 Witch Doctor Base Intelligence difference

There must have been something you have done to your characters, as per definition you start out with 10 points in your primary stat when you create a character and get an increase of 3 per level in your primary stat, this means that at lvl 60 you have gained 59 levels resulting in an increase of your primary stat by 59*3 = 177 points meaning you should have 187 points in your intelligence in total.

I am not sure if the console version of the game still works with the old paragon system in which you gain stats, magic find and gold find per paragon level but if this is the case you should be getting the normal stat increase as mentioned above. (3 primary stat points per level). This is different in the paragon 2.0 system where you can assign the points you get per paragon level to different stats, meaning if you put points in your main stat it increases by 5 per point put in the chosen stat.

All this should make it clear that it is impossible to get those statistics you mentioned without wearing gear. If there is someone with a better explanation for this phenomenon I would like to read it.

I hereby hope to have informed you well enough.
