Android does have lots of games, and some apps that aren’t as easy to use, or as good as in native linux. For example, some painting apps (krita is powerful, but can also overwhelm someone), video editors like capcut or lumafusion, audio apps. For most of everything else, there is a web browser on linux that can do the job better probably, and native apps. But overall, I’d say that Android apps aren’t really that useful on linux, because they’re mostly geared towards apps that you use on the go, while you usually sitting on a chair at home or work when you’re using linux. To be honest, most native apps now have been replaced by a web browser, so either native linux or native android apps are only useful for high end professional usages (e.g. blender, video editing, etc) rather than everyday use.
