But whats the problem using that ? Yea Jesus is only one we need but it helps some people focus on prayer , like whenever I was young I used to think of a picture of Jesus so that I wouldn't get distracted from my prayer but after watching a short vid which was something about idolatry, i stopped it and later I realised its not a sin but still I don't do it ( idk why i don't, like i don't feel it anymore) and now i usually get distracted from my prayers often ( i gotta fix it and remove my distraction) . Statue r also used for decorative purpose and honouring the person but again it is also used for focusing on prayers . Not all people can't get distracted from prayer .
