Well done @EmilBulka!
Please correct:
1 (OPTIONALLY) Please return StatusCode() method as in other controllers eg:
return StatusCode(StatusCodes.Status403Forbidden, new Response { IsSuccess = false, Message = Common.UserExist});
2. In every controller action please return ActivelyApp.Models.CommonDto.Response not only the string
3. remove comments
]
4. change Actively/Actively/ActivelyApp/Mappings/PLayerMappingProfile.cs to PlayerMappingProfile.cs
5. I dont like the way that we name folder structure and files

In folder called blablablaDTO we should have all files namex xyzDTO.cs
6. CreatePlayerInfo.cs has 3 fields but UpdatePlayerInfo only 2
7. please correct intendation and remove empty lines like here

8. I think ForMember() method is useless when property name is the same, please check it and if it not necessary remove it

9. I controllers that you created, methods should use not PUT but PATCH HttpMethod explanation here : https://clockworkjava.pl/2021/02/rest-api-post-vs-put-vs-patch/
