No, it's not relevant, because they are discussing completely different conversion metrics and at different scales. Also, your insistence that less than 1% of viewers will interact is based on the mistaken assumption that 100% of reported views represent someone who actually watched. Real life doesn't work like analytics.
About 1% of the people shown an ad (or any content) will even consciously acknowledge it, while approximately 1-3% of the remaining 1% will interact with it, and then 1-5% of that remaining group will actually buy the product. The 99% who didn't acknowledge its existence in the first place don't actually factor into anything other than how much you get charged for the ad.
The difference between the article and the OP's scenario, is that the OP already filtered the 99% and converted the rest. Now there is only one conversion left, which is to make them into paying customers, which is a much higher rate than 1% when you already have a captive audience.
