You're correct data can sometimes be wrong, but this is mainly in the basic datasets provided, and still exceptionally rare. I once highlight a figure was wrong to their helpdesk, in an obscure money supply aggregate, bt public data that I happened to be pretty intimate with, and their helpdesk were all over a solution in seconds.
For added-cost datasets, they're mainly a reseller for a 3rd party data provider and SLAs need to be checked to see what you're getting.
For checking via other sources, this is a minimum in finance. Reconciliation / validation needs to be done at every step something new is introduced, and just for the heck of it usually anyway.
