I don't know the reliability of these sources, but according to one article[1], as of 1 year ago, US Netflix had ~5.8K titles, totaling 36K hours of content. Another more recent source[2] claims that worldwide, Netflix has ~15K titles, so assuming the same distribution of runtimes, it would be closer to 93K hours of content. So, while you're correct, it's still the same order of magnitude.
