Yeah, pretty much. In actual use (as I understand it), a foal is pretty much just a non adult horse and filly/colt are just synonyms that also specify a gender. What constitutes an adult horse/pony though isn't really any sort of rigid set in stone concept. And there's a bit of gray area around the teenage-ish years.
