At 33 it is possible to make it but it is tough. Really tough. By the time you are employable to will be a couple of years older and despite what is said it is borderline as to whether or not the principal employers of low hours pilots would look at you. There is always the exception but they are few and far between from 35 onwards. I was actually a little older and it took me nearly 4 years to find a position...and I was lucky! There were many periods during that time that I wished I hadn't 'wasted the time,effort and money' and it isn't a happy place to be. The skills you gain aren't really transferable to other occupations either.
That said...it is a great job, it has it's ups and its downs but all jobs have that. Just make sure that you know what you are getting in to and what you stand to lose.
