Yes it is true :)

When you tap all robots, you don't get any currency at all. Regarding your situation I would guess the following happened:

You had around 50 robots. Since there can only be 30 in your town at a time, 20 were invisibly held in the "bank". You went through your entire town and cleared around 40 of the robots: the 30 that were visible from start plus ten of the ones that got moved from the bank to the town while you were tapping the others. That left around ten robots in you town, and those got cleared when you played the minigame and you got the reward for them.

No matter what you do, you always get the same reward, so it's up to you what you want to do. Personally I prefer having all robots cleared automatically when I play the minigame over checking every inch of my town three times every four hours (yes, three times because of the bank). It's one of the best event features ever!
