What a strange question but I'm bored so what the hell
Sussex is rated as top 40 in the complete guide so I imagine the majority of students there are not academically the most gifted
That being said I just did a quick Google and the following celebrities from Sussex Uni appeared:
Jessie Ware worth $6 million
Billy Idol worth $60 million
This proves that is obviously is 'possible' for there to be potential high rollers
Yet you have to factor in that it is really difficult to forecast ones potential and identifying the prospective riches will be hard
So to answer your question, Yes, but it may be unlikely and will depend on your definition of "rich"
