I am surprised they make a statement like that in writing. I think it is best not to rely on that.
“Paid” is not just money. As they state a bit vaguely, it can include being provided with “accommodations and amenities” in the U.S.
(I am guessing that CIC means Citizenship and Immigration Canada, that CBP is sharing information with.)
Just be a tourist if you want to avoid secondary questioning etc.
