90% of my engineer/designer friends have no clue what every financial/equity question imaginable even look like, and even if they had a list of them, they'd have no clue about how to interpret any of the results, or how to tell if the company is feeding you BS.
I mean, I was the first employee at a startup, involved with fund raising, and then founder at a startup, and even I would have a hard time with that.
Not to mention that even if you have a very solid understanding of what things are like when you get hired, it can all change dramatically in subsequent fundraising.
This is just one of many instances where the employee/employer relationship is heavily biased against the employee. And unless clear disclosure requirements understandable by the average worker are put in place, it'll stay that way. As an employee, your options are inscrutable lottery tickets which value can be redefined in many ways at many points in time, and there's not much you can do against that.
