The problem with a statistic like that is that it is pretty much devoid of almost all data that would make it truly meaningful and valuable. That stat tells us nothing of their health pre-Covid, and I’d bet a very large portion of that number were already dealing with health issues (which we already know significantly increases severe Covid). The meaningful number is how many formerly healthy people are battling Covid caused health issues a year later. My guess is that it is a pretty small number, likely small enough that it would be considered even by you to be a “small minority”.
Previous health condition status is part of the dataset, so you don't need to guess. If you want to take that into account, then use the data to make your point.
Thanks for the tip! I’ll let the dataset speak for itself:
“7. Health/disability status is self-reported by study participants rather than clinically diagnosed. From February 2021 study participants were asked to exclude any symptoms related to COVID-19 when reporting their health/disability status. However, in practice it may be difficult for some participants to separate long COVID symptoms from unrelated exacerbation of pre-existing conditions, so these results should be treated with caution. “
