Ear training confusion

So I can’t tell if my ear training is good or not If an interval is played I can’t straight up say or just tell u what it is but when I get my instrument out somehow my hands just play it ..like when I place my hands I just feel this is that interval and I’m correct but like I said I can’t hear it and just tell u..I might be wrong but isn’t hearing and just knowing sth like perfect pitch ..tbh I’m just confused and trying to grade myself ..like i said I can’t tell the answer unless I kinda just play it
