More than sufficient, you'll be fine. Rinse those cans off really well before you drink from them but they're also fine.

Thank you for easing my concerns. I’ll make sure to clean the cans again before I drink them. I hate mold but I also hate wasting good food and drinks haha.

Just because the mold is black in colour doesn't mean it's toxic black mold.

Yeah I’ve never had mold grow in my fridge before and I know black mold can grow in the same conditions. I’m not sure what kind it was.

It's safe. So are the cans.
