Nothing rising to the level of implying and certainly not implying rude.
Just, "I failed the phone screen somehow by someone who sounded 20 years younger than me" might be suggestive of something to self-examine.
But since you're confident that you are fully innocent in the interaction and the rejection is solely due to your interlocutor's naivete and inexperience, then it's no doubt true.
