All were Disciples when our Lord Jesus Christ walked the earth and became Apostles after our Lord ascend ended into Heaven JonAk
A disciple is a follower or learner. Apostle is “one who is sent off”— people on a mission to accomplish something [i.e. the spread of the gospel], while disciples are people following and learning from a teacher or leader. That leads to the common saying that all apostles are disciples but not all disciples are apostles. Excerpted from: http://www.CatholicsBible.com
