Dozens of years of planet conquering by several thousands of Saiyans led to only a few hundred planets being conquered. Vegeta also expected it to take him and Nappa about a month to conquer Earth and that's with book-ending the invasion with full-moon nights to speed things up.
I wasn't suggesting that they would fight all the soldiers of the planet in one single go.
However, we can be sure that they wouldn't have battles against just 5 fighters every time they fought or something like that.
During that period, we can be sure they would fight
many battles against (
at the very least) thousands and thousands of soldiers many times.
Yet, the argument was that just a few hundred soldiers that even Roshi can beat are able to tire end of Z Piccolo so much that a Zarbon level fighter matches him.
So... if that happens with Piccolo, what would happen to Saiyans who are around Raditz's power? Obviously, it would very doubtful that they would have great success at conquering planets with just a few saiyans... Any battle against thousands of soldiers, even if they are very weak, would tire them immensely and leave them extremely vulnerable.
(Also, I have no idea where you got that number for the planets conquered by the Saiyans or the time period for Earth's conquest).

Pretty much this. I have no problem with a Zarbon level guy reaching Piccolo by training.
Freeza after all surpassed SSGSS Goku by training.
Freeza is pretty much implied in the manga to be the being with the highest natural power in the universe, which allowed him to "rule"for many decades without much fuss. Even though his increase in power in the movie is ridiculously extreme for just training, at least it ties into that notion of him being that much of a freak.
A random alien having a similar extreme power-up without any kind of tie-in to any notion of the manga, is much worse than ridiculously extreme.
