Does getting the biometrics letter mean you'll be approved?

[QuantGuy]

Does anyone know if getting the biometrics letter means that the Home Office doesn't have any questions about the application?
That is, when in the application cycle (e.g. before or after receiving the biometrics letter) would the Home Office ask for clarification, more documents, or question something in the application?
Seems like the Home Office wouldn't issue the biometrics letter if they had problems with something in the application or am I assuming too much?
Thanks

Everyone is asked for biometrics and this is done before the application is assessed. It's done in all situations and is not an indicator of anything.
