Cholesterol vs Saturated fat?

The doctor says that I have high cholesterol but I have been eating foods that say 0 mg Cholesterol in the food label, but may have some mg of saturated fat.

What is the difference ?

I’m not sure how I can eat any differently to lower this. I’m already on one cholesterol lowering drug and would hate to have to take another one.

I’m so confused about what to do differently or what to do next.
