[GoT] During the war of 5 Kings, why does Robb Stark alway seems outnumbered by the Lannisters? Doesn't Robb Stark command the North and the Riverlands?

He does, but the North is not densely populated or tightly held. Compare to the Southern kingdoms that have abundant human resources, and the Lannister wealth is legendary - certainly enough to raise and maintain a larger army than could normally be expected.
