Will Non-Grad gets a chance to be considered for CS jobs?

I am 50, a Diploma holder with 1.5 professional certs and have 20 years of experience in the private sector as well as 2yrs with a Stat Board as a manager. After a 1yr+ break, my applications for CS jobs were all unsuccessful.

Will someone from CS HR please advise, realistically, will i stand a chance to be shortlisted for CS jobs?
