    function burn(uint tokens) override external returns (bool success) {
        balances[msg.sender] = balances[msg.sender].sub(tokens);
        _totalSupply = _totalSupply.sub(tokens);
        emit Transfer(msg.sender, address(0), tokens);
        return true;
    }

just wondering what overrride actually does and when to use it

Read about inheritance in the official documentation. – goodvibration Nov 13 '20 at 09:42
And more generally with regards to your questions about Solidity keywords here (like this one) - please search these keywords in the official documentation instead of asking others to do it for you. – goodvibration Nov 13 '20 at 09:43
