No a rolled coin is more likely to land on a heavier side then a flipped coin. A flipped coin is doing exacty that, flipping side to side as to where a rolled coin is on one side and depending on a heavier side. There is honestly no comparison to the two.

The only simularities would exsist if the coin landed on edge and rolled at that point it would apply to the heavier side hitting downwards in most cases.

Flipping is that the coin is quite literally out of control. There is no balance and there is no ryme or reason to the landing of the coin. That is why it is called chance / luck.
