Hello and welcome!
What you want is 3D Modeling + Game programming. That’s a lot but totally achievable.
Start here:
https://www.gamedev.tv/p/learn-unrea…oupon=A525FCB2
It gives a super nice start for people without programming experience: absolute minimum C++ basics needed for game dev, absolute minimum version control basics needed for game dev, then they go into developing using UE4, C++ and blueprints.
I don’t think there’s a better start than that course(I’m not paid or associated with them in any way).
Then this:

One suggestion: do everything they do, never just watch, do all the exercises. Just watching is exactly like watching someone doing exercises in a gym and not doing the exercises yourself. Some exercises in their videos(which are 12-15 minutes long each on average) can easily take you 2 hours of work. Don’t hesitate to rewatch previous videos after you forgot something(you will) and rewatch the same video to be able to do the exercises. Well, if you can’t, then just follow after them and try to make things work. And if you can’t and it still doesn’t work, ask on Discord, Stack overflow, these forums and forums on gamedev.tv. Provide the solution you’ll have on yout github.com(or gitlab or whatever), and someone will help you.
Well, it’s not about programs but about knowing topics. You can make a model(like a box or a gun or whatever) in any respective program and even just assemble bytes manually(in a hex editor). It’s about what you want to do and why, and programs are just tools for that.
So don’t learn UE4 Editor, Visual Studio, Blender, Maya, etc. Learn algebra, geometry, algorithms, data structures, modeling, coding, computer graphics programming, version control systems, general design patterns, gaming design patterns, software processes, etc(you’ll get to know bits and pieces of all of these topics listed above in the 2 courses I linked). Depending on what you’d like to do you’ll need different levels of knowledge in different areas.
For what you described as a simple game, these 2 courses above should be enough.
