SUMMARY

The discussion centers on the mechanics of gravity as it relates to an inclined ramp. When the ramp is horizontal, gravity exerts a force that keeps the marble stationary against the ramp. Conversely, when the ramp is vertical, gravity causes the marble to fall freely. As the angle of the ramp increases, the gravitational force can be decomposed into two components: one that pushes the marble against the ramp and another that propels it down the ramp, with the latter increasing as the ramp's steepness increases.

I know it has something do do with gravity, but not 100% sure of the explanation.

well first think of the two extremes.
If the ramp is completely horizontal, then all of gravity is just pushing the marble against the ramp and the marble doesn't move. However, if the ramp is completely vertical, the marble will fall down just as if it had been dropped in midair.

when the ramp is anywhere there are two different components to the gravitational force then. Part if it is just being pushed against the ramp, and the other part is being pushed in the direction down the ramp. The component down the ramp gets larger the steeper the ramp is.
