As @AndrewS pointed out the US charges more than other countries for the same surgical procedures and worse health outcomes.An Apple iPhone is about the same price in China as it is in the US. But fast food workers are paid much less in China than in the US.
In other words, luxury products scale to currency exchange rates, but basic services do not. This is the observation you are making. The US has such a large % of its GDP tied up in basic services because labor is very expensive in the US, and that's almost entirely due to the exchange rate differences. Other industries just cannot compete.
There is an argument to be made that, at the high end, US services are of higher quality than China's - for example in health care, where the US has access to better technology, equipment, high end medicine, etc. But there's also a great deal of waste.
The better comparison, to not get into trivial arguments over the quality of service, is in basic services. Because anyone can see that the guy working at a fast food restaurant in the US isn't producing better quality service than his equivalent in China. But he's being paid much, much more for it.
This is how you ultimately realize the reason American GDP is so high - it's because average Americans working average jobs generate so much more nominal wealth than average Chinese, even though the work is the same.

So are their healthcare services actually better or just more expensive?
Yes it is obviously related to exchange rates but the prior trend that inflation means currency devaluation has been broken. A RMB devaluation in 2022 and 2023 was unexpected because usually high US inflation means a strong RMB like in 2008. Yet in just 1 month from April to May 2022 the RMB fell off a cliff and then kept falling to November 2022.
