The force of friction is dependent on its weight (or more specifically the force of normal) but not only its weight

When you want to lift it up vertically, then the force that you need is exactly the same as the weight.
But when you push or pull it forward, you need a different force.
Push a golf ball on the table: you need very small force, much less than it’s weight. Suck the same golf ball through a garden hose: you need much more force.
You want to look up “coefficient of friction” in your books.
