Despite Trump's 'marginal' comment, that 7-year-old probably still believes in Santa

Remember earlier this week when Trump asked a child over the phone, 'Are you still a believer in Santa? Because at seven it's marginal, right?'? Who could forget?!
Well, the parents of seven-year-old Collman Lloyd of Lexington, South Carolina (a girl -- it had been reported the child was a boy) filmed her talking with the President:

And, the AP reports that Collman had never heard the word 'marginal' before.
Collman had called the NORAD Tracks Santa program Monday night to check on Santa’s journey delivering toys. In an interview with the Post and Courier of Charleston, she said the scientist who answered the NORAD phone asked her if she would like to speak to the president.
Six minutes later, Trump was on the line. “Are you still a believer in Santa?” Trump asked. When she responded, “Yes, sir,” the president added, “Because at 7, that’s marginal, right?”
Collman didn’t know what “marginal” meant and simply answered, “Yes, sir.” Trump closed by saying, “Well, you just enjoy yourself.”
