Yeah for sure, it's a huge business.
And I'd say that RPG Maker dose count! I don't like being to strict on the qualifying terms, simply: If you make games, your a game dev :^)
There's tons of no-code options out there, you should give them a look (things like Construct game engine, visual scripting in unity / unreal / godot, rpg maker of course, and visual-novels makers like twine), and see if you like making games again!
