another process that does the calls

or seeing it's in wow64, it could create a 64-bit thread and make it call the native syscall instead (unlikely but possible)

Perhaps it doesn't use it at all and just uses windows to look for things

Perhaps it has it's own trampoline to call those functions jumping over your hook

Perhaps it uses a secret hidden driver windows 10 provides to game devs by microsoft

.....

could be anything

Pull the syscall stuff from ntdll.dll for your system. You can easily loop the exports of the dll, find anything that starts with Nt, calculate the offset as needed to the exports code and pull the offset/index and such from there.
