While it's certainly a fun little superstition that we all have a so-called lucky table or a particular live dealer who helps us out during our roulette games, the reality is quite different. The fact of the matter is that, since you're betting real money at these casinos, they're regulated very thoroughly to ensure that every aspect (the roulette tables, the live dealer, etc) is fair and doesn't give anyone an unfair advantage or disadvantage. Even though it would certainly be fun to win some real money due to rigged live dealer roulette, another player is posed to lose theirs for the exact reason. And the best way to avoid being that unfortunate gambler is for the casino to simply place everyone on equal footing.
