From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The documentation says:
To my understanding this isn't even emulation but regular container technology.
Yes, Waydroid uses lxc containers.
Wouldn't some Android Apps require specific builds for x86 architectures? Does Android take care of that?
If you need arm, then you probably have to install libhoudini https://github.com/casualsnek/waydroid_script
libhoudini is optimized for Intel, NDK for AMD, but some apps may be incompatible with one or the other.
A lot of android apps are built using Java/Kotlin, so you don't actually need to care about architecture since the JVM supports both x86_64 and arm64.
There are exceptions to this though, since some apps need to run native code. Those apps would need some sort of emulation/translation layer for the arm instructions.
most android apps are architecure agnostic "java, kotlin etc" and even apps that are often ship "Universal binaries" which include x86, or split builds for arm and x86
