This is possible - he could've sung in school or on his own and found he could sing, but when he told his parents they think he was kidding. This happened to me for a time with juggling - I just kept at it and now it's one of my best side gigs (It has helped me get two jobs on its own). Now, if he said he never heard HIMSELF sing and think if he could do it or not - yeah... that's a bit hard to believe.The goth/opera dude sings wonderfully, but his own parents haven't heard him sing ever? I find that hard to believe. How would you know you can sing and have the guts to try out on national TV is no one else has ever heard you sing?
