Those specifications don't contain the answer to your ultimate question ("will this microphone be OK in the situation that I have?").
Given the name, people might reasonably expect a microphone's "sensitivity" to specify the quietest sound level that the microphone can detect. But instead it specifies the voltage that the microphone puts out for a certain standard sound pressure level (1 Pascal = about 94 dB SPL), at a midrange frequency such as 1 kHz.
This is relevant because loud music or other loud program material, as picked up by sensitive professional condenser microphones, can easily overload consumer-oriented audio recorders. Given the sensitivity figure and some math, you could figure out the maximum voltage that you would expect your microphone to put out, when it's being driven by the loudest sound that you expect to record with it. Knowing that, you could then determine whether or not your microphone is likely to overload the input of a device such as a recorder, mixer or preamp that you might want to connect it to.
