int is neither 32 nor 64. Its width corresponded to a platform’s register width, which is now even more blurred because today’s 64 bit is often too big for practical use and CPUs have separate instructions for 16/32/64 bit operations, and we agreed that int should be likely 32 and long 64, but the latter depends on a platform ABI. So ints with modifiers may be 16, 32, 64 or even 128 on some future platform. intN_t are different fixed-width types (see also int_leastN_t, int_mostN_t, etc in stdint.h; see also limits.h).

Also, don’t forget about short, it feels so sad and alone!
