The intelligence part in AI seems to vanish every time an author tries to make some clickbait article:
For instance, by installing predictive AI into a slot machine, the machine can determine what game to present to the player by analyzing previous interactions between the player and the machine’s features and options.
so in short the "AI" recommends a game based on your previous action and a series of parameters which, what surprised are defined by the the people who are adding the games, because if you're going to tell me we have managed to create an AI model that understands and enjoys gambling I'm going to ask you if we're in 2080 already!
Seriously this is not an article, this is a paid promotion, take a look at the disclaimer:
Jared Thau (the author) is the Founder and CEO of Gameverse Interactive Corp.
I actually understand the casino model in which the algorithm helps to analyze and present a particular game to a player based on their previous activity in the casino but the part of the article that go me was where is said the AI integrated to the casino also helps customers to archive more profit.
It could actually be a paid promotion like you said because even the title was just decorated to be an eye catching one that any gambler might want to read its content.
