I would be genuinely surprised if they weren't.

My data science graduate program had a class that analyzed major data science success stories. The very first one covered how Caesar's Entertainment built models and ran experiments to identify their "most valuable customers", figure out how to predict when they were getting ready to leave the casino, and intervene with incentives and perks designed to get them to stay and keep gambling. And also how all of their competitors rushed to implement their own programs in response.

Look at it from the casino's perspective: their entire business model is centered on exploiting quirks of human psychology to separate people from their money. Expecting prosocial behavior from them is like expecting a squirrel to ignore your bird feeders.
