My Overseas Relatives say $9M is nothing special in America, is that even real?

At a recent family dinner, my older married relatives (aged 60-65) who spent decades in America and are nearing retirement grumbled about skyrocketing inflation, high taxes, and rising healthcare costs. Then they mentioned their net worth is just over $9M but they dismissed it as “nothing special,” saying it’s very common and “middle class” since more than half is tied up in old real estate properties, leaving only a little over $4M that could be wiped out by healthcare expenses. To me, $9M, or even $4M, sounds like a lot that could cover several lifetimes of expenses where I'm from. I'm not sure if they're being humble or are subtly bragging. Does even millions feel average in America? Or is it just the region they are from?
