I don't find reading books appealing. But I do look up things I am curious about and read few news articles I come across. Reading a book isn't the only way to gain knowledge but if they aren't reading/learning about anything then that's a problem.
Reading narratives to escape into the fictional world and skimming articles for information are both literacy (reading). There are many more kinds as well. They all count.
For me it depends, reading books is hard for me because it feels like a chore that never ends. Even if it is a thrilling story, it's just hard for me to focus for long enough to make any progress. Might be ADHD idk. But at least I keep reading news articles and other things that are relevant, because obviously I want to stay informed about what's happening in the world, especially when elections are around the corner.
