At $125/hand times 0.004 times 60, that's an average profit of $30/hour for house from the bj player. Of course, 6:5 is much worse and the take could be about four times that ($120/hour)

Slot machine return is a lot harder to know, but Wizard of Odds has some published numbers from Vegas from 2012 that puts some machines at an average house keep of 5 to 6%. Penny machines may be much higher. Assuming 10 spins per minute, that's 10 * 60 * .05 * $1 = $30/hour. Penny machines might be double that or more.

Again, there's no telling how a casino views one player versus the next, but from this perspective the casino's take from a $125/hand BJ player may be similar to (or more than or less than) a $1/spin slot player, depending on what rules the BJ player is playing under and which machines the slot player is using.
