Exactly what it sounds like. I've been looking for one, but all the replies say that the version does have a JRE, but I cannot find the folder for it. Is there even a JRE? If there is, can you please give an explanation? Thank you!
Yes, that's the whole point of adoptium. OpenJDK has JRE binaries as you can see on their website.
JRE is in bin/java.exe.
