In general the registrar manages, on your behalf, which name servers are set for your doamin in the root servers of the Top Level Domain, in that regard they're always "in charge".
You can confirm they have indeed delegated your domain to your own name servers by either looking up the "whois" records for the domain, or query the root servers of the TLD directly. The latter is easily done with the dig
command line tool:
dig +trace privatmamtora.com
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.1 <<>> +trace privatmamtora.com
;; global options: +cmd

So the domain is running from your own name-servers and the records at GoDaddy are redundant and can be removed.
(Often when you change from DNS managed by your registrar to your own nameservers, the registrar won't immediately remove the DNS zone/records for your domain from their name-servers. DNS updates take time so that allows for a painless transition.)
