Well...they are kinda right. 3k a month mortgage when the interest rate was low, now I imagine it would be closer to 4k per month. Housing prices might not be growing as fast but I haven't seen them dropping.
A 4k payment is a ~$580k house at 7.5%. Median home price is $387,600 as of November '23, for a payment of $2716. Not to say things aren't tough out there. Just that a $4k mortgage is still 30%+ more than what people can expect to pay at the median. This ignores taxes and insurance of course.
An actual mortgage payment would probably be closer to 3,000-3,200 after escrowed PMI, taxes, insurance, on a typical loan.
