Baldur's Gate 3 is based on a mostly faithful recreation of the Dungeons & Dragons Fifth Edition system, adapted for PC and PS5 by Larian Studios. As a CRPG adaptation, Baldur's Gate 3 does make some changes to the tabletop system, however, one feature that has remained almost completely untouched is proficiency.
