On eBay for certain scammy sellers, but not as a general rule.
And on Amazon, certainly not for items sold by Amazon or part of Prime. Again, only scammy third-party sellers.

Not quite a scientific study, but I always sort by cheapest just to check and see this pattern every time.
The distinction you make is technically correct, but a does not lessen the scale at which it is happening.
Even if there are tons of scammy expensive-shipping listings, if people are almost never buying them and they almost never get surfaced in search results, it doesn't matter.
But I've also never even tried sorting by cheapest, because default sorting by relevance has always worked for me.
