Hi, welcome to the world of game development.
Since you mentioned you are extremely new i will take the freedom to assume your programming and art skills may be low or limited. But do not fear, thankfully already exists lot's of tools some pay some free that can help you make games without studying an engineering. (You might want to visit forums and tutorials though).
Sorry if my post os a bit overwhelming. You don't need to buy/learn all these tools. I prefer to just show you some options i think may help you, then you just choose from.
Let me recommend some links to get resources.
Open game art. Good webpage to get free art resources for your games (3d models, sprites, textures, music)
Also here in itch.io you can find an asset store with both free and pay resources.
Extra music.
Some tools to create music without knowing sh*** about musical theory.

Visuals

Some advices:
-Do not pirate the tools. 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. If in the future you need to change the tools, it will be less painful.
-Always start small. Not big games, don't try to make a GTA or a COD first. Start small.
-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.
