None of those guys were going all out against him in the fight, Oro refers to how they are "toying" with him, which they obviously are (they stand around, chat, once in a while throw out a tech, and then stand around some more under Oro's control). The reason Hiruzen is able to seal them is that he uses a tech that Oro didn't recognise, and Oro never got serious (because he didn't realise Hiruzen had such a technique, and couldn't conceive how he could beat him).
Let's remember too, that in order to use said tech Hiruzen had to die. What a victory. *eye roll*
Not even close to Hashirama's feat of having a fight to the death with EMS Madara and the 9 Tails (and winning)... notice, he was alive after the fight too.
