or merely carelessness on your part, but you implied that the things you emphasized were all requirements for those jobs:

Applicants must meet one of the following requirements in addition to the Basic Education Requirement:

Applicants must meet one of the following requirements in addition to the Basic Education Requirement:
a. One year of appropriate professional experience at least equivalent to the GS-5 grade level; or
b. One full academic year of graduate level education in an appropriate field, or any equivalent combination of experience and graduate study; or
c. Completion of all requirements for a bachelor's degree which meets one of the following SUPERIOR ACADEMIC ACHIEVEMENT STANDARDS:
1. Standing in the upper third of college class or major subdivision at time of application; or
2. Grade point average of 2.9 of a possible of 4.0 or its equivalent for all courses completed at time of application or during last two years of undergraduate curriculum

[emphasis mine] I think that gives a good idea that you don't, in fact, need to have prior experience or a graduate education.
