For example, slot machines in Nevada are only legally required to pay back 75% to players on average The most important word in Vegas is that last one...average. As long as all the machines in the house average 75% in payout, the house is in compliance. What it means for the average player is that the low-denomination slots (nickel, quarter) can pay significantly less than 75%, and by setting a few high-denomination slots ($1/$5/$100) above 75%, everything comes out clean. So it's an even worse situation if you play the cheap slots.
