Unlikely. I had similar issue and finally found my old password. Did you have 2f auth on?
Why not talk to Google Support - you can prove ownership in multiple ways...
I once got banned by Google and found it difficult to find a place where I could contact support to reinstate my account. I did find a phone number but spent nearly an hour getting bounced from person to person until I found someone who was just a general support woman who couldn't handle my request due to the 'wrong department'. Instead I was asked to read one of the many FAQs you can find online on Google's many sites. They might as well have said 'Google It' in the phonecall.
