Probably not. Oumuamua, the first extrasolar object we've tracked through the solar system, has a hyperbolic excess velocity of ~30km/s, or 1/10,000 of light speed.
So in a billion years, such an object could travel 100k light years, or the diameter of the entire galaxy.
Sub-relativistic interstellar travel is very slow on human timescales, but fast on geologic ones.
