Okay, I'm no wasp expert, but that sounds plausible.

...but it sounds like at least some parasitic wasps do sting humans, even if their sting isn't a big deal.

• Megarhyssa is a large wasp found on declining or recently dead hardwood trees between May and July.
• It parasitizes horntails present in declining trees, but does not injure trees.
• Harmless to people and ignores people when possible.
• If mishandled, it may sting to protect itself.

• Although ichneumonid wasps appear dangerous due to their large size, they are not harmful to people.

• The wasp may jab with its ovipositor in self-defense. This will generally result only in a minor wound.

And that thing looks like it's got a larger ovipositor than the one the wasp has in OP's picture:

The ovipositor is 2-3 inches long.
