That depends. On paper, windows 10 might seem to have a lower minimum requirement. But in practice, unless the hardware limits the maximum amount of RAM (think certain netbooks)
I'd not touch any windows system with less then 4GB of RAM, and generally the default nowadays is more or less 8GB RAM. That is for only for internet browsing and a bit of office stuff, and to make it a bit future-proof.
Requirements for virtualbox come on top of that, that is the same no matter which OS runs on your virtualbox host.
Although back to your question, for Mageia you can customize much more about the operating system, if you only want to use a very minimalistic graphic environment then you can go with a lot less RAM.
The minimal requirement is more or less a dependency for the graphical installer, the installed system can be made to use less RAM if you really want that.

Are 16 GB RAM only recommended for VirtualBox in my case? Is 16 GB RAM enough for the entire computer with Mageia with Virtualbox and the Windows 10 program? How can I estimate this?
It might help if you could mention what program that is. But yes, in theory if the manufacturer recommends 16 GB RAM that would only be for the virtualbox guest, so if your host uses 8GB and the guest 16 GB overall you would need at least 24GB RAM physically.
I'd say as you want to use virtualisation frequently, you shouldn't go with less then 16GB RAM, as a generic rule of thumb. That should also be already sufficient so that you can run a VM the whole time without issues.
But performance will depend on what you actually run inside that VM, and another factor would be if you use a spinning disk (HDD) or an SSD.
Although I'd not save on RAM, considering that it's basically really cheap on its own - e.g. 32GB only cost slightly above 100$.
