For tournament columns you'll need to add "tourney_" to the start of the database field names. I'm surprised it let you build those columns in the Holdem Tournament Player Statistics section.
These should be OK:
cnt_won_wo_sd =
sum(if[not(tourney_holdem_hand_player_statistics.flg_showdown) and tourney_holdem_hand_player_statistics.flg_won_hand, 1, 0])
cnt_hands_wo_sd =
sum(if[not(tourney_holdem_hand_player_statistics.flg_showdown) and tourney_holdem_hand_player_statistics.flg_vpip, 1, 0])
