Why did black connect as the last move couldn’t black have ended with one more territory?
No. A stone in atari doesn’t get you any points.
By any chance in any game after ending the game and while counting points all the territory filled by prisoners or captured stones and still remains stones to be put it in the board ?. Or simply any negative points winning in this case white gets zero points.
Scores don’t go negative – if the count works out that low, it just gets capped at zero rather than dropping into the minus.
Are there situations where you see that it’s not worth to start or continue a Ko fight? Or is it always a good idea to make the opponent react to my threats and reduce his territory?
Of course! A ko is worth fighting only when what you win is bigger than what you burn along the way. Every threat you play is a one-time resource.
Rough rule: if the ko is for the life of a big group or a huge chunk of territory – fight. If you’d lose little by giving it up and you’re short on threats – try to avoid it. Also, if the opponent has far more ko threats than you, starting the ko is often just paying them to use those threats.
