Most number of Top players are from Russia

Yes it's true. I know Russian very well. I can also read and write not just speak.

Any ideas why they are much better apart from the above?

During the Cold War, chess gained added importance in Russia. Chess provided a mega-metaphor for this psychological war, one that derived added significance from the game's important role in Soviet communist society. The Russians might have lagged behind in military technology or economic competition, but over the chessboard they reigned supreme. Many Russian leaders were avid chess players, which is something to note. They were constantly on the lookout for new talent, which certainly paid off at the championships. (: 

Not to discredit other nations, however. India, Ukraine, Israel, the U.S., and many others are not to be ignored in the world of chess. They may not have the common knowledge of Russia, but they still hold power over the chessboard.

It is because Russians like chess more, so they are naturally the best at it compared to other countries. The USA is the best at baseball, basketball, and American football because Americans enjoy playing it. Same goes for how China is number one for ping pong, ect. 

Yeah, do you see any nation with skill in cricket that could compare to India? I don't think so.

During the Cold War the Soviets had huge training camps to train GMs all those who were trained passed it down to their kids etc. and most top russian players nowdays are from those camps

How about England, WI, Aus, NZ, Pakistan, Bangladesh. Most former colonial states play cricket

Oh I didn't know that!

Yes, but the top player (Virat Kohli) is from India along with (I believe) the top team in the sport. But yeah, I suppose saying no other country could compare was an overstatement on my behalf.

Of course, this should all be taken with a grain of salt, as someone who doesn't follow sports closely, let alone cricket. 

Glad to teach people somthing new! You can search it up, thats why Bobby Fischer was such a big thing, because the Russians were training kids since birth, and Bobby without as much training as the russians came and won!

Why don't other countries do the same? IS anyone stopping them? 

Well there are camps, but they are mainly for advanced players

There are many top players from India. 

yes, but to creme de la creme is with the Russians

There is also a great deal of good books in Russian on stuff like mathematics and electrical

engineering. I plan to order some books and study them. 

First of all Soviet Union had very good educational system and yes chess was supported by government too. But it is pointless without players with potential. In Soviet Union people were very interested in reading and chess. Why? Because it was hard to get books and life didn't provide entertainment like in west. Western children don't like sitting at the board for 5 hours long because they can spend their time better. Some time ago Karpov gave an interview where he said that in his town they had a chess club where workers played till night after hard working days. Chess was their only entertainment. It is not hard to be best in the world If you have such people enthusiasm.

I wrote something but never mind.

My request for my Russian friends:

Please appeal to your booksellers, especially my-shop.ru and chitai-gorod, and ask them

to arrange international shipping for their books. Thank you.

Update: Ok, I see that the website books.ru has a large selection of books in Russian

and it ships to Israel. I will try to order books from them and hopefully things will turn out well.

I think you have said some valid reasons 👍
