I realize that of all people, I am no expert on parenting or marriage.

The line is a self-effacing disclaimer: the speaker signals humility and limits of authority before offering views on family life. By foregrounding her lack of “expert” status, Brzezinski frames any ensuing comments as personal experience rather than prescriptive advice, implicitly acknowledging how culturally charged and judgment-laden topics like parenting and marriage can be. The phrasing “of all people” intensifies the admission, suggesting she anticipates skepticism or criticism and wants to disarm it. In a media context, such a caveat can function rhetorically to build trust—positioning the speaker as candid and relatable rather than moralizing—while still making space to discuss values, mistakes, or lessons learned.
