Most of them, yes, but not always. You'd be surprised. Sometimes, it can be quite mundane.

It's come in useful to inform certain decisions that I had to make at times. And, interestingly, it sometimes activates in combat, but again not necessarily when I want to.

[It's a bit frustrating sometimes to be the only Star Master with a passive ability.]

On the other hand, I have fewer chances of being drained of energy when that happens because it is quite brief and not as intense as what most other Star Masters can do.
