If A is correlated with B, you usually see them happen at the same time, but changing one won’t necessarily change the other. For example, ice cream sales and deaths by drowning are correlated because people buy ice cream and spend time in pools a lot in summer.
If A causes B, then both happen around the same time and if you manage to prevent A, you’ll automatically prevent B. For example, eating food causes you to feel less hungry; if you stop someone from eating, they’ll stay hungry.
The reason this usually comes up is that someone saw two things happening at the same time and thought they could affect one of the things by altering the other. For example, someone notices that people who drink red wine are often healthy, so they’ll start drinking wine in hopes of becoming healthier or depriving their enemies of wine in hopes of making them sick, without checking if the wine actually causes the health.
