Mosconi would start a match of straight pool by moving 100 counters over. Willie Mosconi used to come to the high-roller nights at my dad's place in Flatbush. On pool, YES! My mind went there instantly! I guess you could do straight pool as a skill roll, Art(Pool) + DEX, shot for shot.

Unplayable–kind of like they needed something so came up with something, although their heart isn't in it. Hey, OP, I don't know if I mentioned this but the Mongoose book Scoundrel has a four-part resolution system suitable for any wager that is person-on-person. I think you'd be better off adapting task chains to existing games. I don't think you can have IRL gaming though, because then there are no skill checks to be made. Sure you can evade the surveillance, but there are plenty of high-stake games that don't happen inside casinos. This would also holds true on high-tech worlds, with their hi-tech casinos. These are all skill checks–a huge task chain! Part of gambling skill is money management (INT), psyching out the other players, whatever. Part of gambling is backing off on the free drinks (INT formidable). Part of gambling skill is knowing when to walk away (INT), and when to run (DEX). IMHO, this is a great game mechanic, even for a Vegas in Space campaign. The attributes used vary, from intelligence, to endurance, to dexterity depending on the task. IIRC correctly, in T5, winning takes a skill check balanced with an attribute.

I say it is important to remember that you are not playing against the house–you're playing Traveller, meaning that in-game gambling isn't random like IRL gambling.
