I think a key difference between cyber safety and cyber security is that cyber security often involves skilled professionals, whereas cyber safety is ethics and safe that students can begin at any age. Same with cyber awareness. Students from P-2 will not be using 2 factor authentication or keeping up to date with policies and procedures. However, they learn how how to be careful with devices, apply safe settings and being thoughtful. At this young age in primary students can be taught a lot about cyber safety, but cyber awareness and security might be introduced later. Cyber security is more about the devices and cyber awareness is more about data, whereas cyber safety is more about the actions of the person.
