No. A DOS program certainly _starts_ as a 16-bit program (since that's the only kind DOS knows how to run), but it can switch to 32-bit protected mode right after that, and run most of its code as 32-bit. That's precisely what DJGPP programs do: the startup code begins as 16-bit, then switches to 32-bit protected mode using a DPMI function.
