Anyone skilled has special abilities. A skilled mechanic from the future might build a flying car. Then a skilled rapper can write a cool song about it.
A skill is a well-earned talent, like being able to ride a bike, write a script, or spin a basketball on your finger. If you have skills, you're skilled! Congratulations. Being skilled in something usually requires practice. A skilled politician wins elections. A skilled hitter in baseball has a high batting average. A highly skilled job is one that requires special training. The opposite of skilled is unskilled, which would apply to someone without a particular talent.
