Using ML in my line of work is becoming more and more prevalent. I keep thinking someone is going to us it for predictive data in MLB, if they aren't already. Any time you do predictive modeling without ML, you're limited by the number of data points you can use and when you have to pick data points, the model is prone to bias. ML eliminates the bias (for the most part) because it's not limited by the number of data points you can use.
