This is correct. In addition all sales at gun show from a licensed FFL to a customer currently also require a background check. Currently the main two kinds of transfers that don’t require federal background checks nationwide are private party sales and gifts. Eg. Selling your neighbor a shotgun or gifting your dad a hunting rifle. I believe these were both carved out exceptions as a result of the limitations on the Feds due to the commerce clause. Several states have tighter restrictions.
