thanks. Does the high memory begin to be used only after the low memory is used up? If yes, what is the advantage of that? If not, how do you explain my example, where high memory is zero?

That's a good point I hadn't noticed. The 64 bit kernel architecture reorganized memory management so that it all appears as a single block for simplicity.

Do you mean in a 64-bit OS, the high memory is always zero, i.e. there is no high memory?

Yes, as I said, they reorganized the memory mapping to make it simpler and more efficient.
