No. So the Attack Titan has the power to see their successor's future. When Grisha touched Eren, he saw the future that Eren was going to lead. Even found out about the future when he kissed Historia’s hand during the awarding ceremony (it was the end of season 3 part 2). He saw the future because of Historia’s royal blood and the Founding Titan’s powers

He didn't know, he knows everything after kissing historia's hand on the ceremony, but his titan power allow him to send an order or show something to all ymir subjects in the past or future, that's why little eren already had that dream about him and mikasa, because it's a dream sent by future eren
No im so confused pls anyone enlighten me so from the start, from when he was just little child, eren already know abt the future?
