It seems like a very subtle difference, but I think sqlite3_column_count will return the number of columns returned by a prepared statement regardless of whether there is data available to get with sqlite3_column_* functions, whereas sqlite3_data_count requires that there be a current result set row available due to sqlite3_step most recently returning SQLITE_ROW.
