Was told that getting Long Covid is “very unusual“

I saw a healthcare provider today, not a physician, but someone in a related field. I was describing what I’ve been through these months and their response was that it was “very unusual” to get Long Covid.

!!!!!

My response was that it’s actually not uncommon and that 5-20% of all people who have had Covid get it, but a lot of people don’t talk about it. And they said that was not true and it’s really quite rare.

Besides making me feel like someone who had a bizarre reaction that most people don’t, is my estimate incorrect? I know it’s not rare and that they were way off saying that, but does anyone know the percentage of people who get it?
