Yes, there may be possible duplicates, but I am talking about the STRUCTURE of Unix/Linux operating systems with folders like bin, home etc. Unix/Linux-based operating systems are supposed to have its structure, OS X is also supposed to have it. Does it?

There is really no such a thing as a standard Unix/Linux filesystem structure. Multiple attempts have been made over decades to define one, but no one really adheres completely.
Even between Linux distros you will find some differences.
Still most Unix and Unix like systems at least have a lot of stuff in common, if only to make porting software between them easier.
MacOS derives most of its underpinnings from BSD Unix and is no different in that regard as this ls -l
