Selecting a specific country in the Organic Traffic Insights filters not only data from the SEMrush database but also from Google Analytics and Google Search Console for that region.

This statement is true. When you apply a country filter in Semrush's Organic Traffic Insights, it refines the data pulled from all integrated sources: Semrush's own extensive database, your linked Google Analytics account, and your connected Google Search Console account. This ensures that the traffic, keyword, and performance metrics you see are specific to the selected geographic region, providing a more accurate and localized view of your organic search performance. Without this comprehensive filtering, the data would be aggregated globally or based on the default settings of each individual tool, potentially skewing your analysis for a specific market.
