That's certainly a typo, with the terms switched.  (though not a very
important one)

Effectively, yes.  They are commonly used interchangably.  Neither is a
subset of the other.

If you want to get technical, telecine is the machine used to transfer
film onto video, while pulldown is the process of converting the ~24fps
film into ~30fps interlaced video.

You are close.  There's no progressive "frames" involved, as TV shows
are filmed interlaced (one alternate field is captured every 1/60th of a
second to make 30fps interlaced video).
