so can a light player not be comfortable with the spotlight ? or a void player have an obsession with learning all the secrets ?

I would say, yeah. Classes and Aspects, when it comes to personality, it’s all about broader strokes of the personality rather than hyper-specific stuff. Like Time, I bet there are Timebound people that aren’t specially rambunctious fighters, even though that’s what the Time description says. So a Void Player may want to unveil mysteries, but maybe in doing so, their hyperfocus on mysteries could mean they’re not interested in learning EVERYTHING, rather, just the interesting, weird bits. And a Light Player can definitely be comfortable not being in the Spotlight, you can easily take Luck and Information as a more focal point than Spotlight. I mean look at Aranea. Sure, she took on a more Light = Relevancy and Spotlight role with the Game Over timeline, but up until then she was like. Offering advice and getting ignored when she rambled too much about stuff. All she wanted was to talk to people about stuff, not to necessarily be relevant. Although she did like talking about what was relevant at the time.
