Yes, atmospheric loss driven by solar wind is a very slow process. It’s the only reason why anybody entertains ideas of thickening the Martian atmosphere… the loss is slow enough that if a civilization has the means to do that kind of planetary engineering, maintenance to offset losses is trivial.
Intuitively I’d expect it to be faster in the case of Earth due to it being so much closer to the sun but I don’t know this for certain.
