I would recommend starting with an engine–it doesn’t much matter which and follow several tutorials. The exact amount will vary based on your programming experience and game design knowledge. Once you’ve followed some tutorials start trying to connect concepts from different tutorials to make something new that you weren’t explicitly guided to. After you’ve done that a few times, start a new project and try to make something from scratch and use reference materials, documentation, and tutorials to help you when you get stuck.

Start small. Now even smaller. Tic tac toe is a reasonable first project. It will teach you how to use the UI library, user input, game state, scene transitions, basic AI for a computer opponent, etc.

Then do some game jams. There’s a lot hosted all the time on itch.io. You don’t have to finish, but it gives you good practice, let’s you see what’s possible in a weekend, and let’s you connect with others that love game dev.

I’ve seen a lot of comments encouraging you to try out Godot. It’s a great engine, and with its resource library and active community it can be a good choice, but it doesn’t hold your hand. There’s very little logic that is pre-produced and ready for you to tweak. You start with nothing and build what you want rather than starting with a template (though there are templates available in the resource library). I’ve used a lot of engines and Godot is my personal preference, but depending on your experience Scratch or Unreal may be better options for the easy of use and active communities/tutorials.
