I don't think older people have much idea of how tricky it is to start out now. I'm 32, and when I went to uni fees were set at £3,000 a term. You could also get what was essentially an interest loan to help cover living expenses. I've been paying mine back directly from my wages for 7 years and still have over £10,000 of student debt. Students now pay up to £9,000 a term, and their living expenses loan is charged at commercial interest rates. I've no idea how someone who doesn't have wealthy parents can afford to go to uni these days. I doubt I could afford to do it now.You don't seem to have a huge amount of choice though. All kinds of jobs which my class mates could have accessed with a reasonable secondary education record require some kind of further education these days. You won't get an apprenticeship without going to college, you can't get a job as a carer or nursery nurse without having the right SVQs etc. I realise they're not university level qualifications but they do require accessing paid education.
Not doing so leaves you minimum wage jobs. I live in Fife, which is hardly expensive (unless you live in St Andrews). My rent is £400 pcm, council tax is £100, and energy £60. A quick Google suggests those on the minimum wage take home £960 a month, leaving £400 a month for everything else. You're hardly living the high life on that, im not sure how you then save the £7,000 - £11,300 you'd need forca 10% deposit in this area on that.
As others have said, access to a mobile and the internet are considered essential these days. My employer only accepts applications by email, and only sends out any overtime by text message. Without both internet access and a mobile I couldn't have applied for my job, and I couldn't get overtime. And thats not considering your credit rating. Credit agencies expect you have a credit record these days, and not having taken any credit is a hinderence. I was actually advised to take out a phone contract and a credit card to build by credit rating if I wanted to buy. Seems such things are 'essential' these days if you wish to own.
