The appropriate design for testing the significance of the difference between the means of two different groups (poker players vs. blackjack players) is an independent samples t-test. A related samples t-test would be used if the same group of players played both poker and blackjack. A one-sample t-test would be used to compare the mean of a single group to a known standard or population mean. A z-test would be used if the population standard deviation is known, which is typically not the case in most real-world situations.
