The house edge for live dealer games is lower than most of the other games at the casino. The percentage of the bet that you will lose for each round varies from one game to another and your hand.
For example, when playing Spanish 21, the first hand of the shoe has a house edge of less than 1%. Roulette has a house edge of about 2.7%, while 3 Card Poker has a house edge of 3.37%. On the other hand, the table games section has higher house edges than most of these percentages.
