As soon as you ask "Is it precisely true ...", we know immediately that it must
not be, and we know that our task is to search your version of the statement
for the hidden gotchas.
I don't think Gauss stated his "Law of Electricity" in terms of 'lines of force'.
Seems to me more likely that he stated it in terms of the surface integral over
the closed surface.
But even if you want to state it in terms of 'lines', then there are a couple of
small problems with the way it's stated in the question above:
1). Instead of the "total" number of lines, it would have to be the "net" number
of lines, and it would have to say something about the lines crossing the closed
surface in the direction normal to it, in case the closed surface isn't a sphere.
2). Gauss talked about just plain charge, without regard for positive or negative
as quoted here. And corresponding to that item, he wouldn't have mentioned the
"outward direction" either.
Equally in all direction.
IF it is (they are not all enclosed), then it is to prevent air currents from messing up the results.
Area enclosed by the PV (pressure-volume) and TS (temperature-entropy) diagrams shows the work done by the system.

If there is no water crossing involved 900, to $1200, for traditional car hauler. Enclosed trailer, maybe $2000. Chuck....
