According to music teachers, there is no person in the world who is devoid of a musical ear. It's just that some have more developed this hearing, others less, and still others it is in an embryonic stage and requires a lot of labor. The vocal voice is a derivative of the ear for music, although its development requires a lot of effort.
Try singing a simple melody, perhaps. the usual scale. Most likely, the first time you will not be able to do this, because your voice is not coordinated with hearing. And hearing, in turn, is not yet sufficiently developed. Sing again and record your voice on the recorder.
Listen to the recording. Without exception, all people have the first reaction to their voice - panic horror. Firstly, you do not recognize your timbre, since in the usual state you hear yourself through the bone, that is, without some overtones. If you just record your speech, the situation will not improve fundamentally, but any other person will recognize your voice on the recording - it is an external voice that everyone around you hears.
Secondly, on the recording you will hear falsity, which you did not feel when singing. If you recognize her, then everything is fine, you still have a hearing. If not, you can also rejoice: perhaps you naturally have developed coordination of hearing and voice.
If you are not convinced by these reasons, ask your musician friend to teach you a diagnostic test lesson. Let him just play a few notes, which you can repeat with your voice, and then give his opinion. Most likely, it will be in your favor.
If you can't find a friend, contact the teacher-vocalist of the music school or college. Teachers of institutes will take a large amount of money even for a trial lesson, and the quality of teaching will not necessarily be higher than that of colleagues from another educational institution.
