but to say truth i am pretty sure admins or workers from electrum wallet behind .. because i got a window to download wallet directly in wallet ! .
No... It wasn't the "admins or workers". Unfortunately there was a "bug" in the Electrum code that meant that a "bad" server could return any message it liked to a client and include links. Scammers found the bug and then exploited it to send phishing messages advertising the fake versions from fake github sites 
This bug was then patched to prevent the phishing messages from being displayed.Refer: https://github.com/spesmilo/electrum/issues/4968
funds are gone for sure ...
Unfortunately, yes... that much is certain
