Hi brickbones. Welcome to the world of game development. What games are you interesting in develop? already choose/learn and engine?
Some advices:
-Always start small. Not big games, don't try to make a GTA or a COD first. Start small (like a VN or a prototype not for publishing).
-Do not pirate the tools you use. If some tool is commercial, buy it, to avoid any legal problem in the future.
-Do not use AI as a replacement. AI is not a replacement, is a tool, or something more like an assistant. It may create some small code and pretty drawings, but when you need to create things bigger and functional, you will need the knowledge (in arts, music, etc) or a professional's help.
-Read licenses and ToS. Many of the things you can or can not do are explained there. Also, how much a big company can affect/control your work. (Example: Unity situation, so beware of SaaS)
-Don't marry with anything. Learn how to do stuff, not how to use a specific tool/program. If in the future you need to change the tools, it will be less painful.
-Remember to take rests from time to time. Don't overwork yourself. (The only person responsible for your well being in yourself.)
I hope i didn't scare you, wasn't my intention, just give you a little hand/head start. Don't be afraid of making question. There is no stupid question. Everybody was a newbie once.
And good luck.
I made a copy paste from another post. haha. Anyway, wish you luck.
