I have imported a sound file into Matlab using [sound,fs]=audioread('....')

I need to find the sampling frequency. I think that is fs, however when I import a different sound, my fs value does not change? Is there a difference between sampling rate and sampling frequency, and if there is how do I find the sampling frequency from the audiofile imported?

Sampling frequency is the inverse of sampling rate. You can also relate this to the physics relation between period and frequency of a wave. According to physics, the relation between period (the time taking for a wave to complete a cycle) and frequency is {frequency = 1/period}.

Yes, fs is the sampling frequency. Sampling frequency and rate are related to each other: frequency = 1/rate. And it is not strange that two files have the same sampling frequency. Most of the audio signals are recorded at a similar sampling frequency, e.g., 44.1 kHz.
