I'm guessing a very small subset of trainers make that much. An awful lot of AI training is done via Mechanical Turk like systems that pay pennies per task. They may work out to more than $15/hour on a per task basis but rarely can anyone get a continuous flow of hundreds of tasks per hour, so grossing even $10/hour would be considered pretty exceptional.

Edit to add reference [1]: "An analysis of the platform published in 2018 revealed that of the 3.8 million tasks analyzed, which were performed by 2676 workers, such workers earned a median hourly wage of about $2 an hour, while only 4 percent of workers earned more than $7.25 an hour"
