That does not appear to be entirely correct.

DNSSEC "only" protects the authenticity of the DNS data received - that 
e.g. is that the data has not been altered on its way from the server to 
the requestor. It still is full clear text and can be looked at by any 
interceptor between the server and the requestor.

If that is not wished for, e.g. for reasons of privacy, one could deploy 
DNS over TLS ("DoT") and/or DNS over HTTPS ("DoH") to protect one's 
queries - be them plain DNS or DNSSEC - from any third party inspection.

As such, both approaches are pretty much orthogonal to each other as 
they serve different and independent purposes.
