Those numbers are not really accurate given the variation in rules and slot payouts.

For example, many of the strip hotels now offer 6:5 payout on blackjack, which reduces the player's odds.

And the slots vary widely. Some casinos have 99% payout on $1 slots, some pay 98% of 25cent slots, and other pay what you've posted. Casinos are free to set the payouts as they wish, and the numbers are published monthly by local trade rags.
