which careers are risky to list in Bschool application

I was reading a thread titled Essays Entrepreneurship and few of the members pointed out that your post mba career goals should not be too risky.

So I was wondering as to how the admissions determines which career choices are risky!

For example: In the annual placement data of Tepper school, they list careers such as Project Management(0.61%),and General Management(5%) so on ...

Now does it mean if your pre-mba career is project manager, then is it seen as risky by the adcoms because post mba placement data is not so high as compared to other careers?

Another doubt is, If you state your post mba career is say product development management ( Iam not sure whether it falls under the product marketing (10%) or production management (0%), it would be helpful if someone could clarify!). Does it mean your post mba career choice is high risk?
