Earlier quoted context omitted.
Yes, but for different reasons. Playing an instrument or sport means you're more likely to have a non-poor family with parents who have time to spend with you.
I think having parents who can help you develop a growth mindset is awesome and something generally reserved for upper/middle class parents. The part where your mind grows comes from practicing. So practicing video games is the same as practicing sports or instruments, the games encourage you to keep pushing yourself in the same way that a coach or teacher would.
Video games are a non-social controlled environment with obvious and predictable goals, similar to gambling. Gambling encourages a person to keep pushing themselves for a positive outcome but that alone does indicate any form of personal advancement.
Sports and music require development of skills, often with coaching by a human, and requiring long periods of independent practice without any kind of immediate feedback. In sports it takes years of investment to get good (less than excellent). If a given video game took years of investment to complete the current level almost nobody would play that game.
