I consider your questions has been answered, regarding how wallet work.
1)if bitcoin system Same in all over world why some wallet can control fees and others cant like Blockchain.info ??
About fees, wallet developers have arranged how a wallet set fees according to the network condition.
Some wallet are better than others for sure, I recommend electrum wallet and nothing to complain about this wallet.
But, I've been using Blockchain.info wallet for a long time and the last few months it has an upgrade which you can set customize fee for sending bitcoin.
