Similar to the concept of DEX or Decentralzied Exchange, is there any gambling site which allows users to import private key and play games directly from their address? Or allows users a wallet on the platform with private keys so that user can withdraw and deposit money into account anytime without the approval of the site representative?

There are few decentralized sites based on tron blockchain which offer you such services of betting directly from wallet. The one I know about is mentioned below at the bottom. I have not myself tried such platforms as I find it risky to give my wallet info with private key attached to it. You can also try EOS gambling daps but they seem to slow and Tron based platform beat them anytime, thats my personal opinion. The link as promised is
