Does the mass of a marble effect how it moves?

Yes because I think how a marble moves depends on its weight.  Some can be light and move fast and roll straight or it could be a heavy marble which is harder to blow on.   It will not move fast and it might get off track because it slows down and loses its balance.

When given a force what happens to its motion?

When given a force it moves it in a forward direction most times.  When the object is light, it moves so fast it just goes straight but very often the ball gets off track and turns.
