Lukas is correct here unfortunately, the vast majority of players of audiogames are indeed themselves blind because the experience of mainstream graphical games is lacking so much in access, and is either impossible or takes so much sound and memorization it is in no way an equal experience to that of sighted gamers. This is why a lot of the audio only games for Pc such as crazy party, shades of doom and swamp are very  deliberately targeted at a blind audience, or at least, the vast majority of their players tend to be blind.

That being said, there are games now on the Ios ap store who have expanded the audience rather. Generally if a game isn't presented as "a blind game", and is visible on a platform like ios, it's got more chance of being played by fully sighted users, albeit still a fraction of those who play graphical games.
Such games include the games from somethinelse such as pappasangre 1 and 2, audio defense zombie arena and the night jar, blind side, and a blind legend, as well as audio addventures which function like interactive audio dramas such as codename sygnus and the inquisitor games.

Also note however, that as well as self voicing audiogames,a large proportion of games played by visually impared people have textual output as well as, or instead of sounds, output which can be read by a screen reader, including the aclaimed a dark room and king of dragon pass for ios as well as muds and interactive fiction games. Indeed frequently if a screen reader can get hold of some of the text of a game it is possible to add access, making games like browser based rpgs and several games on ios accessible. Often these also feature sounds.
I'm not sure if you'd call these audiogames or not, particularly something like adventure to fate, but there is definitely more in the audiogames cannon these days than just specifically self voiced games produced uniquely for blind people or bvisually impared people's attempts to play mainstream games via tortuous memorization.
