Dwarf: Cancer. I guess they both wear armor? And dwarves are kinda crabby? And for some reason I always think of crabs as greedy. Maybe too much Moana influence.
Dragonborn: Libra. The scales of justice!
Elf: Sagittarius. The archer. Because Legolas.
Firbolg: Aquarius. The water-bearer is a nice image for the peaceful firbolg. Also they seem kinda New-Agey, and the Age of Aquarius and all that.
Gnome: Capricorn. The water goat? WTF is a water goat? This thing never made any sense. Gnomes can have it; they like jokes, right?
Half-Elf: Gemini. They are of two worlds.
Half-Orc: Taurus. Big and strong. Bull's strength. Charge!
Halfling: Scorpio. Because some of them have a nasty Sting! ...Get it?
Human: Virgo. She's, like, just a person. No bow and arrow, no jug of water...
Tabaxi: Leo. Of course.
Tiefling: Aries. Of course.
Tortle: Pisces. Well, they are both scaly aquatic creatures, and that's something, right?
Barbarian: Taurus. See "half-orc."
Bard: Pisces. Honestly, I just left bard until last and Pisces was all that was left. Fish are cool though, right? They're shiny and they move around a lot and some of them can sing. I think. Maybe that's whales though.
Cleric: Capricorn. OK, so the classes aren't going as well as the races. This sea-goat thing is kinda mystical, and that makes total sense, honest.
Druid: Leo. I dunno, I guess it's a better Wild Shape option than "sea goat."
Fighter: Aries. I think I got confused because the survey said "Ares," as in the god of war, which would have been pretty obvious.
Monk: Aquarius. Yes! Because in the monastery where you trained, you had to balance jugs of water on your head, or fetch water from the well using two buckets on either end of a stick that you would put over your shoulder, like Raiden in the Mortal Combat movie. It totally works.
Paladin: Libra. See "dragonborn."
Ranger: Sagittarius. Of course. This one actually works. Good thing rangers don't automatically specialize in two-weapon fighting any more.
Rogue: Scorpio. Because some of them have a nasty Sting! Well, the burglars do, anyway. And the assassins, they use poison. It's close enough.
Sorcerer: Virgo. I feel like this one makes sense but I'm not sure why. I guess maybe because the sorcerer is "pure" magic, and virgins are pure? That's pretty weak, honestly.
Warlock: Gemini. Because the patron is sort of like a second character; the warlock is conjoined to the patron. They're best buddies! Together forever, just the two of them!
Wizard: Cancer. I give up.
