Assuming perfect spheres there is similar or the same friction with the surface it rolls along for both and much larger air resistance for the bowling ball.
Mass doesn’t matter because it is a component of Force which is initially equal for both. The acceleration and speed will be different for both to make forces equal.
The bowling ball will lose more of the force than the marble regardless of which slows down faster.
The bowling ball has a lower friction to mass ratio and will therefore slow down less
