It seems that way sometimes, but the drops later game really do get much better than the early game. I usually can get 1-2 alchemy (or equivalent) on my higher ranked duders, and I don't come close to that in early game. Like, you will never get a rare in early game that is worth anything, and you are far less likely to find Chromatic or 6 socket items (you flat out won't find 6 socket items), or a unique. All told late game gives much better rewards. Those fall out all over the place in late game, you rarely see them early game (and they are pretty useful, you will need them for getting good potions.) And of course all of this ignores the additional issue of not being able to find much +quant items at low level.
I'm not saying that you don't get some crazy streaks early in the game, you totally do, but it's wrongheaded to think that those streaks are superior to later game rewards. Their RNG needs some work, but I don't think it's really broken. I don't see any serious players farming low-levels, and with the kind of min-maxers I play with....if that worked they would do it.
