Is there anymore uncertainty

Almost every day we hear people claiming that there lies uncertainly in everything and everywhere; life, relationships, future and anything and everything.
And most of the times or atleast sometimes these people are those who boast or atleast feel that they are very near to finding the ultimate truth.
But my point is how can you be near to the Truth if you believe that uncertainty lies everywhere. And still their claims are taken true.
You, when can only see uncertainty and not the certainty that lies in it, also believe them. And its because you yourself cannot calculate and determine certainty that is in uncertainty.
So therefore you believe any body who says that every thing is uncertain, especially future.
But if you are efficient and have powers to calculate- not mathematical but ability to asses your strengths and weaknesses, you can see the certainty. Not only see it you can also calculate it.
That's what you do in a game of chess. You try being a move ahead than the opponent. You count the moves that opponent would try in answer to your one particular move. And those who can calculate it more efficiently always win.
Now if you believed that everything is uncertain, you would have to learn to calculate it. But still there are people who are hard to be convinced. So they must continue reading. Here's an example for them. There are hundred balls placed side by side on a table. If you take one more ball and hit it on any of the balls placed on the table. ????????????
The result everybody knows. Almost all the balls or atleast most of the balls would get displaced or would undergo a movement. But till now you don't know what the new position balls would take place.
And that's the reason why you say that uncertainty lies everywhere.
When you would hit the ball from a different angle, the movement would be of a different kind.
And if you hit with at similar angle and at same speed more than one time results would be similar.
By simply keeping in mind the weight of the balls put on table, the ball you choose to hit with, speed of the ball thrown, distance of the ball thrown from the table and using the laws of mathematics and physics you can determine what would be position of balls on table afterwards.
At least one who knows physics and mathematics can easily do it.
So if you could not calculate it that does not means that there is certainty in everything and anything. It seems to be uncertain because you cannot see the certainty. But if you can see, everything is certain.
That is true for balls and same goes true for life, relationships and future.
