If the OP means that everyone can 'rogue' just because they can pick locks and disarm some traps, or possibly even because they can disengage and hide as well, all of those statements are true in the EA of BG3. Even the 5e rules support most of it because they are all decided on a D20 roll against a known DC (difficulty check) between 1-30. With lower DC checks even a party member with a negative modifier has a chance to succeed, but that does not make them a rogue. A rogue is so much more than a lock picker and a trap finder even though he should be doing those things as well because if he or she is a good rogue they would be out front sneaking around and scouting the area, planning ambushes and devising battlefield tactics. Every PC in the current build of the game that is not a rogue can sneak and hide, but they do it badly. Your party should never be surprised in combat if you can absolutely help it because of the disadvantage on dice rolls and a rogue played well will not only fill this role for you, but while the enemy is advancing on your party and focusing all of its efforts to kill Cale, your crafty rogue will be doing what he does best, killing them all from the shadows.
