se is standard java, ee is container specification, which can also be considered as a series of jar packages.
Strictly speaking, tomcat does not belong to ee, but should be classified as a servlet container. Belonging to ee are containers such as tomcatee, glassfish, and jboss.
As for many domestic tutorials, which are said to be "javaee programming guide", basically none of them are qualified to be called ee. It would be more appropriate to rename them "java web guide".
As for Java, it is only divided into two versions: se and me. Of course, there is also server jre, which is not easy to classify (server jre is not ee anyway).

javaee is a series of specifications. The container you use implements some specifications and some jar packages, such as tomcat
If you use tomcat as the server, there are related javaee jar packages in tomcat
