This is true if and only if the test design is poor.

That is the worst possible test plan.  It totally lacks organization and
there is no hint to define when the feature set has been covered.  Ad
hoc testing is a useful addition, but it cannot replace all the standard
tests that have been used by the industry for decades.

If you run literally hundreds of tests designed to ensure that your
product conforms to ANSI/ISO standards then the bugs that are missed
will be few and far between.  Unless you are bad at designing tests.

Designing tests is busywork.  Desiging tests is boring.  Nobody wants to
design tests, let alone interpret the results and define correct
baselines.  But testing is very, very important.
