Low earth orbit is in space ('outer space'), so unless they have been to other parts of space not sure it's more correct - perhaps more specific, but I think the more general correct claim wins out.
If they'd previously been up in sounding rockets, or high altitude aircraft, or like a Blue Origin sub-orbital hop we would likely have an interesting discussion here - I will take anything that has surpassed the McDowell line as being 'in space' but think making orbit is more impressive.
