Is the High Availability of a system same as Availability in CAP Theorem?

I'm confused with the definition of things

In my view High Availability is the property of a system that aims to ensure an agreed level of operational performance and usually is expressed as a percentage of uptime in a given year.

On another side Availability in CAP theorem state that in a distributed system, reads and writes would always succeed even when network connectivity is unavailable between nodes.

Therefore I made the assumption that these two things are absolutely different.

If this true, could we say that the distributed system may be High Available and don't have a property of Availability in terms of CAP and vice versa?
