Some text is not translated
Arduino IDE translations have been made through community contributions, and not all of them are complete. You can see the status of each language at Transifex:
If the language isn’t changing
Make sure you fully restart Arduino IDE.
On macOS, closing all windows will not automatically quit the application. If the Arduino IDE icon is in the Dock with a small dot below it, the app is still running. Right-click on the icon and select Quit to quit the app.
