No. Singleton is not an object, it is a class pattern.
"Singletons are objects that exist globally and are the only one of
their class." - Is correct
The rest is not. The Singleton class pattern puts constraints on exactly
how many instances can be created, not the total number that are
created, if that was the case then the majority of objects in WordPress
would be Singletons because they are only created once. There are no
Singletons in the WordPress library, actual all of the WordPress class
library follows the normal object practices.
Searching Google for "Singleton object" only comes up with the Pattern.
The Singleton is a pattern not an object, if anything it is a class
methodology.

Corrected the definition of Singleton to be:
"Singletons are objects that exist globally and are the only one of
their class; if one instance of a class is created per request, this
instance is a singleton object. "
