I say leave it. Don't reduce your chance of getting paid work just because some smug clown on the internet wanted to score a psuedo-zinger by yelling at his television screen.

If anything, change 'probably' to 'might'. Confidence is good, but some people could take 'probably' as an imputation on their ability to comprehend the subject matter. I'd always aim at "That was just the beginning. Whip out your chequebook and then you'll REALLY see what I have to offer" rather than "You sound like you're in trouble."
