Yes the thermosphere only contains a tiny fraction of atmospheric mass.
The thermosphere, which is located above the mesosphere, contains only a tiny fraction of the atmosphere's mass. Despite its low density, it can reach very high temperatures due to the absorption of solar radiation.
Ozone layer contains a fraction of mass. It is made up of ozone gas.

They have a large mass, and they have rings.Gas giants have enormous atmospheres, it may be said they consist only of atmosphere.

The mesosphere is a layer of the Earth's atmosphere located between the stratosphere and the thermosphere. It is composed mainly of air molecules, with a mass that varies depending on factors such as temperature and pressure. On average, the total mass of air in the mesosphere is approximately 0.1% of the mass of the entire atmosphere.
The Sun contains about 99.86% of the total mass of the solar system, which itself comprises a tiny fraction of the total mass of the universe. In terms of the universe as a whole, the Sun's mass is negligible, roughly estimated to be around 0.0000000000005% of the total mass-energy content of the universe. Thus, while the Sun is the dominant mass in our solar system, it represents an extremely small portion of the entire universe's matter.
A soap bubble, for example.
The air mass of the thermosphere about 15 cm. of air per inch!

troposphere
Asteroids do not have atmospheres because their masses are too small -- their weak gravity cannot hold gaseous molecules. Some asteroids have tenuous regions around them which may contain more molecules than the space farther from them, but these can scarcely be called atmospheres. Most moons, including Earth's Moon, have virtually non-existent atmospheres. Even the planet Mercury, with a mass far greater than any asteroid, has an atmosphere only marginally denser than a vacuum near its surface. The only moon with a substantial atmosphere is the large Saturnian moon, Titan, which has a mass 1.8 times as great as the Moon.

troposphere
The total mass of air surrounding the Earth from the uppermost thermosphere down to the troposphere is estimated to be around 5.15×10^18 kg. The majority of this mass is concentrated in the lower layers of the atmosphere, with the troposphere containing about 75% of the total atmospheric mass.
Multiply the mass fraction by 100.
Because the mass of the planet holds it down.
