emm.... if you give me your discord i can write you a PM in Discord :D
we could make some exercises and source code for you learn how make EXE apps for windows with C++ Builder
once we have something made, you can experiment with it for make other added things to it
the thing is if you dont know nothing of how code things is better you going learning C languaje as stardard for deal with C++ Builder
i can guide you and give you tips, but once you know how manage Rad Studio C++ Builder is amazing belive me
but if your goal is make 3D games etc, is better you learn Unity or Unreal Engine, the problem is if you dont know nothing of how make games will be difficult cos this engines also bassed in source code in C# and C++ so some knowdledges of basic programming is always good.
i see better you start with C++ builder and games stuff basics fordwarding until 2D games, then you can use your C/C++ acquired knowdleges in Unity or Unreal for make 3D games
i said that, cos starting with a C/C++ compiler and IDE you learn other things (with me) like for example kind of variables, game structures more complex for handle things of game in the own code, code flow control structures, and much other things that helps you more than if you take Unity or Unreal without know nothing of C# or C++
also fit the possiblity you find C++ builder so fanzy that you preffer make Apps for windows in the classic style of a management app
