Everyone who went to convents, do they all get good jobs and have their own business ?

i sat the SEA this year an my first choice was 'holy name convent' i past for 'diego martin central sec' and i am still happy bout that.. and then my mother was telling me that.. 'oh, i didn't have the marks to past 4 there & only rich children from private schools an thing does past for there and when they finish they have they own business or working in them big time jobs'.. is that tru that when they finish there, all of em have big time jobs and they business an thing..?
