X and Y are playing a game.   Initially there are three bundles of   matches, consisting of 2021, 2022   and 2023 pieces. Each player in his   turn chooses a bundle B and removes   a positive number of the matches of B   such that the number of pieces of   bundles still form an arithmetic   sequence. The player who cannot do a   legal move loses. Determine which   player has the winning strategy.

it is confusing. You call a player B and later, you say "a bundle B" and "the matches of B". What is B?
