Did I install the right version of java?

Java™ SE Runtime Environment (build 1.8.0_201-b09)

Java HotSpot™ 64-Bit Server VM (build 25.201-b09, mixed mode)
Mac os 10.14.4 mojave

You may verify yourself through the section in the docs on prerequisites:

The documentation says to use 32 bit but the version I got says 64 bit?
Does not exactly match the documentation.
java version “1.8.0_121”
Documentation showed this
Java™ SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot™ Client VM (build 25.121-b13, mixed mode)
Since I am new a complete beginner, I do not want to not have the prerequisites wrong

Not helpful

On most PCs (AMD/Intel processors), 64-bit java will be fine. A later version will also be fine (if not preferable).

There are a few specific issues with 64 bit on arm architectures (RPi, Pine64 etc).
