Boruto couldnt even beat one of the jonins that he faced in the latest episodes with Konohamaru instead he needed to be saved , i even doubt he would be able to do something against " the Mist assassins " the one who attacked Sakura - so how am i proved wrong ?

The difference between a Jonin like Konohamaru and those two Chunin is huge, as shown when Kakashi dropped them in about 2 seconds no diff, so of course he wouldn't do as well against Jonin as Sasuke did against Chunin...
That clip from the forest of death, the fire jutsu used is waaaay more impressive in the anime than originally shown in the manga...
So sasuke loses to orochimaru, and Boruto kills a God with a single Jutsu, and who's stronger?
The point is Sasuke can't see Boruto's disappearing rasengan, even with his sharingan, so he's not going to try and dodge it, he's gonna assume Boruto sucks because Sasuke is super arrogant, like when he first fought Lee thinking he was a badass and Lee No diffed him.
AND once again! My point isn't even that Boruto is necessarily stronger (Which he is if you compare fresh out the academy Sasuke to even still in the academy Boruto) My point is that Boruto is that strong without training, when Sasuke a genius! had to train hard everyday since he was like 5 to reach that potential.
Not to mention that Boruto is academically A LOT smarter than Sasuke also, as Sasuke had to cheat to pass the written test of the chunin exam (which was the exam's intention) whereas as Boruto who took a similar test, which was ramped up to be so difficult the only way to pass was to steal the answer sheet, a test everyone else in his class, including Shikadai and Sarada, had to cheat to pass. Boruto took the exam without cheating and got 100% and he never studies and never trains.
But yeah Boruto would probably solo the Mist Chunin..
