It's much closer to the advice to run antivirus, use a firewall, and apply updates. Exploits are discovered, but there are often mitigations available before fixes come around. By applying the mitigations (AV, firewall, adblock) you can prevent at least some of the exploits until fixes (browser updates) are released.
