I got really bad luck... or? What do you think?

yeah, that is weird.

It seems like they decided to go for the +2 bonus. Then instead of expanding, randomly guessed you were in that direction? If you weren't, they could always airlift the stack when they found you.

There is another 2 bonus in your direction, this is why you met. Just bad luck you were in the way of quite efficient expansion.
You cannot expect strategic outcome with those settings.

Well, arguably you should keep in mind the power of stacks in random distributions. Turn 1, attacking everything with 1's, if he happens to border it, he already know where you are for example. The following turns you remove all your armies (aggressive expansion). You are overexposing yourself, so to speak. Not just on this map, but on more played maps do this apply a bit more perhaps.

Sure, you can claim you got unlucky. BUT you also made the choice to go for the 4. You could have gone for the 2 instead. In which case you would have met in a perfectly even position. The way I see it, you took the risk of going for the 4. However, this time that risk backfired. In other words you happen to make the wrong strategic choice. Not that you could know where he was. But you rolled the die on him being far away.

TL;DR
I call you a n00b in a nice way. You picked the risky (this time wrong) strategy and lost when the die didn't give you a 6.
