No, it does not protect from that. Stub resolvers (i.e. DNS clients) fully trust recursive resolvers by design and don't validate DNSSEC signatures.
In theory the client can validate them but, for various reasons, pretty much none of the implementations do that.
It also helps when your ISP is MITMing your attempts to get accurate DNS information. That happens all the time, though most of it is just sending you to advertisements when you're supposed to get NXDOMAIN.
