I wonder if the pamphlet's changed or I'm misremembering. I distinctly remember Math 123 and Math 114 both explicitly excluding Math 55 (It's also worth stating that Math 122 and Math 113 are definitely not freshman courses). But regardless I'd be very surprised to learn a Math 55 student took Math 114 or Math 123. I would also be surprised (although less so) to learn of a Math 55 student in the 130 series.
The Math 140 series have only become more serious courses in the last 10 - 15 years or so IIRC. The 240 series was generally where to go for serious mathematical logic courses (and generally is where you would go after e.g. a first 140 series course in set theory anyways).
