Ravensbourne, as a student, I am afraid you are simply not in touch with the reality of how tough it is in the industry out there, as you will rapidly discover when you graduate.
You are correct in saying that many fresh graduates might end up in wedding/corporate video production or an office job but they simply will not walk into a production co-ordinator job. That is a skilled position which is highly sought after and not one that a recent graduate can just walk into without working for some time in the business. Paid jobs as Production Assistants and Camera Assistants are also highly sought after and you will absolutely not get a job like that in the mainstream media straight out of University. Unpaid work experience is the first thing you will do if you aim for the mainstream media - that is simply a fact.
It is also true that moving to the mainstream of TV and Film production from the wedding/corporate sectors is extremely difficult, mostly because those industries do not value the experience and skills that you might pick up doing that kind of job. You also cannot legitimately become "self employed" in the proper meaning of that word - although if you mean by that that people will be picking up occasional bits of work here and there, then that is a more accurate way of describing the reality.
Also, when you say that "the 96% statistic is not entirely accurate", what you should be saying is that it is totally and utterly baseless when it comes to any measure of how many people get into the industry in any form. That is the case because no-one has done any research to back up any claim of how many people are in media related work within 6 months of leaving. A more accurate guess however would be that, after two years, there will be more Ravensbourne (and other) graduates not working in the mainstream media than are.
Speaking as someone who does actually know how the real world is - it really is as hard as people make out. It is also not simply a matter of getting work "if you really want it". Determination is helpful but third in importance to careful planning and sheer dumb luck. And if anyone is in any doubt about any of this, I do suggest they talk to people who actually work in the industry - especially Producers and Production Managers. you will find that what I have described above is, I'm afraid, the reality.
