The odds of another space-faring civilization with roughly the same detection technology of us finding the Voyager probes is infinitesimally small. However, any civilization that has managed to reach our Solar System (or just beyond it) most likely has technology we haven't even dreamed of, and could possibly detect it with Star Trek-esque "sensors".

The bigger issue with the Voyager probe is that even if some other aliens did manage to find it, the odds that they would be able to replicate a phonograph in order to play the record is possibly a bigger hurtle. In the end, it's a neat symbolic touch for humans on the verge of going to space, but the most likely alien race to recover Voyager is us.
