It sounds somewhat reasonable and you just are not the candidate. From what it sounds like, it would be like applying for a job as a pool lifeguard but your only experience around pools was from YouTube. They want someone who has handled that item before not someone who says “let me take a crack at it”
That’s not the case at all. Where did OP say they had training on the product but not the specific brand? They just said they were familiar with the product but never used it.
