That wouldn't be possible without a corresponding behavior in those above the median age as well. If what you said was true and there's a disproportionate group of people below the median age leaving the industry without an equal number of people above the median age leaving, then you'd get a constantly rising median age over time and at this point that age would have be considerably older than 31 years. I am not disputing that the game industry has a lot of churn. I'm disputing that the game industry has substantially more churn among younger people than older people and that the churn is significantly different from the rest of the software development industry. It's not so much that young people are uniquely exploited and leave after a couple of years, it's that the number of software developers doubles every 5 years so that there is a huge imbalance of young people in the industry in general.
