And now I'll copy-paste what I wrote in another thread:

History of Gamblers and Pirates in The FF Series:
Setzer (FFVI) was the first true Gambler. He had the Slot command and used cards, dice, and darts as his weapon.
Cait Sith (FFVII) was also a Gambler, with a Slot Limit Break, though he used megaphones for weapons.
Selphie is a Gambler (FFVIII). Many people overlook this since the Jobs of FF7-8 characters aren't really apparent and we have to rely on Limit Breaks and weapons (e.g. Zell & Tifa are MNK, Quistis is BLU, Aeris is WHM. Oh, and despite Tifa's Limit having slots, I would not define her as Gambler because all other slots involve getting a combination which produces an attack. She has a slot reel saying: Hit, Miss, or Yeah!, which basically notes whether she peforms that move, not at all, or does it with a critical hit). Selphie's Limit is named Slot and involves 2 variables: which spell and how many times is it cast for 0 MP (well, 0 spells consumed since FF8 lacked MP), with chances of up to 4 special attacks coming up. Slot was Luck based.
I think she was the first Luck-based Gambler, both Setzer & Cait Sith's Slots were rigged against you for certain Slot moves (see Gamefaqs FFVII Limit Breaks FAQ or Algorithm FAQ, I forget which and MasterZED's document on Setzer's Slot for all the details).
FFIX had many characters with dual Jobs and subjobs. Garnet was a SMN/WHM (she had a greater Eidolon selection and a smaller selection of White Magic), Eiko was a WHM/SMN (she only had a few Eidolons, but many Wite Magic), Amarant was MNK/NIN (MNK command, claws, but also could use Throw). Quina, I would argue is a BLU/GAM because she had 1 feature of a Gambler, her weapon dealt random damage between 1 and her STR stat. No other character's weapon had a damage formula like this.
Wakka (FFX) seems to be a RNG-Gambler combo. He can hit birds and has good accuracy with long-distance attacks, but his Limit Break involves Slots which inflict random statuses. People mentioned FFX-2's Lady Luck, which is a Gambler Job.
The ability Throw Gil, GP Rain, Spare Change, or whatever it has been called has appeared in FF5,6,7,9. Not sure about 10 & 10-2.
As for Pirates, there has been no Pirate class in FF, but many Pirates have appeared in the series, a few have joined the party, but they have all had the Bare Job or been blank states. FF1 had Bikke the Pirate, who sent his crew to fight you, you win his ship in battle. FF2 has Layla and her pirates. She attacks you, but you defeat her crew and she joins you and gives you her ship. Most FF2 characters seem Jobless, though some you can see the Jobs of (Minh- WHM, Josef- MNK, etc). Anyone can equip anything and use any spell in FF2. FF3 has Pirates, but they don't fight you, but they give you their ship if you can solve the problem of Nepto blocking access to the sea. FF3 had a job called Viking, BTW, which played a lot like FFXI's PLD, melee with very high DEF and weak STR (as opposed to Cecil's uber-PLD from FFIV). FFV had Faris and her pirates. And that's been it, though Al Bhed had some pirate characteristics, sailing the seas, but they were more nomads than pirates per se and didn't have the pirate culture or ethos.
People may hate Gambler was dressed up as a Pirate or a Pirate is just a shell for a Gambler, but hey, it could be worse. The Job could involve a Taru sitting atop a giant stuffed moogle and its weapon would be an Instrument (bugle) it would use to provoke its oversized moogle to pound the enemy. It would be like "HULK SMASH!" only in pink. And a hexagun is better than that or throwing a beachball at the enemy or wielding a giant eating utensil (nunchucks or dice, cards, and darts would have been cooler though).
