A 20 year old house I looked at over the weekend has 3 large
skylights. The original owner says that none has ever leaked. I've
always been under the impression that all skylights eventually leak to
one degree or another. Is it realistic to think that some have not
over a 20 year period?

Anything penetrating the roof CAN leak, but everything does NOT leak.

The building I live in has skylights in all units, installed at least 20
years ago. Of the two units I've lived in, none of them have leaked
(each unit has 1 large fixed and 1 smaller openable skylight). My
neighbor's skylight leaked during the last rainstorm, but that's the
first leak I've known about in the building. So no, if properly
installed and maintained, they shouldn't leak.

A lot of what gets called 'leaks', is really condensation on the inside
of the skylight dripping down and staining the edges of the opening. Not
as much a problem with modern dual-layer bubbles, but dirt-common with
the 1960s frosted bubbles that were popular for several years. Since
they skylight is often the high point in the room, the heated air gets
up there, and if there is a sudden cool-down outside, well, you know how
it works. The cheap 1960s aluminum-framed windows had similar problems
with staining the sills.

Yes, it IS possible. Can't remember the brand right off hand, but
there is at least ONE that meets that requirement.

I remember now - it is VELUX. If installed according to their
instructions they will NOT leak.

Well yes & no.

House I stayed in for a year had two fixed Velux skylights. Leaking a
little after like 18 years I was told. Put new roof on and redid skylights.
Actually I reused the same Velux metal flashing and trim. Put down WSU,
Waterproof Shingle Underlayment typically used at eaves for ice issues, per
Mike Guertin's "Roofing with Asphalt Shingles"/Taunton Press. Realigned
step (side) flashing, roof cemented all old nail holes, renailed and roof
cemented nail heads. No runs, no drips, no errors in the year since. Very
heavy northeast snow area.
