Does the film counter point to the number of photos taken so far, or after this current shot?

I know this is a dumb question, but I recently inherited my first film camera, a Rollei B35. After loading the film, I had to fire the shutter a couple times to get the film counter in the window to “1”.

What wasn’t clear to me at that point however, is whether the numeral 1 denotes that a capture has already been taken, or whether it is telling me that I am about to take the first photograph.
