Of course it is. PS has had a career as a presenter and doing comedy on cruise ships before Bid. There's no way anyone could sit through a stumbling performance full of mispronounced words etc. Nor would Bid have offered him a job if he kept fluffing sales pitches in his auditions.
Also, notice how he NEVER stumbles over any of his opening show "fanfares"? Or any of his jokes?
It's definitely a ploy to make the more elderly and vulnerable viewers buy. "Trust me, I'm just like you". He's in his early 60s, but to hear him talk he apparently acts at least 85!
