Other than the TikTok-headed part, the phrase could easily be applied to at least as far back as the 80s (NES) depending on definition of game-playing. Before then, there was foosball and pinball. Nevermind the kids that play card/board games. Also, while not staring at a phone implying smart phone use, it was often said about teens having a phone growing out of the shoulder from them constantly being on the phone with friends.

So, yeah, kids these days...are just like the generations of kids before them.
