If the study and/or article mean "nonprescribed" when using the term "off-label", then the study and/or article are misleading.
The survey cites numbers for children's prescriptions and estimates of adult off-label use. That latter would still be prescribed, but the study is claiming that the prescriptions aren't consistent with FDA certification, which would involve deviations from that certification as I've discussed above, citing FDA terms.
Your preception may be accurate. But it would require either the survey reported on here being misrepresented, or a much larger nonprescription use, which does not appear to have been the study's focus. Either way, you're proposing a possibility without specific supporting evidence.
