I shouldn't worry too much about age.
Better to become a commercial pilot with 5 extra years on the clock than to become one and spend the first 5 years of your career unemployed, dissheartened and struggling to remain current/enthusiastic.
For those starting out in - say 1998 like myself with the exams - things were OK. There was work about, it was always hard but at least you heard of people getting jobs. Everyone I worked with as a PPL instructor in 1999 now has a decent flying job. We stay in contact a bit and everyones happy with their lot. It has been a good 5 years.
For someone starting out last or this year the contrast might be quite stark. You could have the same aptitude, go to the same schools, network just as hard and be just as plausible at interview. And yet you are going to struggle like hell and its going to get you down. If what you are doing right now gets you down a lot then perhaps its merely out of the frying pan and into the fire. If however you currently have a happy enough lot at work I suggest you aim to enter the market in a few years time. The difference it makes to your career and your outlook on flying can be marked.
Remember there are a heck of a lot more people apply for ATPL exams than ever unfreeze an ATPL. There is a reason for that and it isn't pretty.
As I said earlier though. The market is starting to move just a little bit. If MYT keeps trundling along ( I think they will ) then there will be a bit of hiring this winter. Which 12 months ago would have been to the more optomistic end of my expectations.
Good luck,
