That’s the message they choose to use externally. I would guess they had somewhat higher hopes internally, and would have been at least somewhat disappointed if it had exploded just after clearing the launch pad. Whether they’re truly happy with this result probably will depend on their analysis of what went wrong. If they can find the cause and it’s easy to fix, they’ll be a lot happier than when they can’t figure out what went wrong, or when they can figure it out, but preventing it requires a huge redesign. But yes, this is the nature of rocket building. Things do get boom fairly easily.
