While it's true the 386 could run in 32-bit mode, it took a while for software to catch up. Wolf3D for example is a 16-bit program but was most definitely targeted primarily at 386 systems which were then all the rage :)
Well yeah, but practically no commercial DOS software made after 1993, especially games, used 16-bit x86 code anymore, even if they weren't necessarily protected mode programs. On the converse, almost everything using protected mode was exclusively i386 32-bit code, including Doom itself. The good thing about DOS was that while it didn't do much of its own, at least it left the programmers plenty of freedom to put the OS aside and do almost whatever they wanted, including running 32-bit code on a 16-bit OS.
As for the 386...well it WAS primarily designed as a 32-bit extension to the x86 family, perhaps you're confusing it with the crippled 386SX variant (16-bit data bus, 24-bit address bus), which still qualified as 32-bit, technically.
