Depends on what you mean. Default kernel has 32 bits support enabled,
but base system don't contain any 32 bits apps/libs.
There is a special ia32-libs package which provide a few 32 bits libs
allowing you to run some 3rd party 32 bits apps. Those libs are installed
into /usr/lib32.
So debian is full 64 bits, with a minimal 32 bits apps support.
