A 10% chance of a job, having spent vast sums of money on an integrated course, sounds slightly better than normal odds whether you are 20 or 36 years old!
What they actually mean is that you might be at a disadvantage in the initial career path that the integrated schools try to provide - A very expensive course and type rating that might lead to a form of apprenticeship with a budget airline and for a tiny proportion (when times are good), a chance to be a cadet with BA or another similar dream airline job.
Luckily that career path is not your only choice and it would have been a bad choice anyway in the current economic climate as the big integrated schools are being fairly unsuccessful in providing their graduates any help at all.
You can spend half as much on modular training and actually complete it quicker than integrated if you do it full time. At the end of your training you can try to work your way up via the instructor route and corporate (where your age and life experience will be appreciated) and once you have an unfrozen ATPL your age will be less relevant. The career change is a big risk and will never make you much money so don't waste your current savings lightly and think very carefully about whether you really want to take it.
