Is there a clear line between a world losing it's atmosphere to space AAaaaannnndd a comet?

No, the Earth's atmosphere is being slowly stripped away by the solar wind. The atmospheric loss is somewhat slowed down by the Earth's magnetic field which diverts the solar wind away from the atmosphere. The Earth's magnetic field is fluctuating right now, and it looks like it's getting ready to flip, so the magnetic field is weakening, and that might lead to a greater rate of atmospheric loss. It'll only be weakened for a few thousand years, which won't really make the overall atmospheric loss all that significant.
Now, if you're asking whether a comet strike on Earth resulted in atmospheric loss? Some might have escaped, but again it's going to be minuscule. The mass of a comet is much less than the mass of the entire Earth's atmosphere. If you displace a mass of air equivalent to the mass of the comet hitting the Earth, then it'll likely get displaced, and most of it will likely fall right back down to Earth, and only a small amount would completely escape.

Earth is losing a miniscule amount of its Atmosphere all the time
But the Same is being Replenished just the same by our active Earth
Even a Comet strike would punch just a mere hole in the Aymosphere
Which would be quick to fill up
Even from the Comet itself

Planets and dwarf planets don't hsve two tails like comets do. William Hershel thought Uranus might be comet at first, until he and or his sister Caroline plotted the orbit and there was never a tail. Uranus DOES hsve a global magnetic field.
Not a clear line, a slightly fuzzy line.

Yes. One is a world losing it's atmosphere to space.
The other is a Comet.

An atmosphere's resistance could burn a comet before it strikes a fatal blow to the earth.
