he means winning tries have a cost, right?

A considerable cost in the quoted case, yes.

Thanks.
Any difference between a game being finished and being decided?

As always, a full quotation would be useful.

For example:

"After c8(Q) the game is decided" implies that there is no realistic way that (presumably white) will not win. But the game is not finished as black might struggle on.

On the other hand:

"The game is decided when one side checkmates the other" is a more literal use of "decided" where there is no difference from "finished".

Thanks
In:
Naturally, there is a logical explanation for this phenomenon, and it consists of the increased activity of the white rook and the possibility it has gained of accessing Black's remaining weaknesses, at the same time driving its black counterpart into passivity.

Does it consist of 2 thing or 3 things?

Only one thing !

What is it?
I thought it was
1-the increased activity of the white rook
2-the possibility it has gained of accessing Black's remaining weaknesses,and
3-driving its black counterpart into passivity.

Yes that's right, but the author has linked the first two to suggest that they are strongly connected and by using "at the same time" has indicated that the third is a more separate thing. So I think you are exactly right to ask "is it two things or three things". But there is no definite answer to your question: the author has written the sentence leaving that a bit doubtful - maybe he even did it on purpose like that.

It depends what is meant by "things".

What's the difference between
centralized pieces
and
central pieces?
Thanks in advance

No difference.

What's the difference between
White's position is clearly inferior
and
White's position is clearly weaker?
ُThanks in advance

the actual win is still in doubt.
means
the win itself is still in doubt.?

Thanks in advance

Yes. That's correct.

What does it mean if a continuation is positive for Black?

Thanks in advance
