If you toss a coin 20 times and it comes up heads 12 times, does this mean that the probability of getting heads when tossing any coin = 12/20 or 60%?...

If you toss a coin 20 times and it comes up heads 12 times, does this mean that the probability of getting heads when tossing any coin = 12/20 or 60%? What is the probability of getting heads in a coin toss equal in real life? Why was this outcome different? What would you expect to happen in the long run (i.e. if tossed a coin 1,000 times).
