What are the key differences with houses in comparison to signs?

For example I have a 10th House Stellium. 10th house is ruled by Capricorn which means I will have Capricorn like traits but obviously it’s not that simple right. For example I have Jupiter in 8th House which is ruled by Scorpio which means obviously there will Scorpionic energy in that planet but I assume there’s more to houses than simply the sign that they are ruled by.
