Can someone explain how this young man become a GM ! ?
That player will have been above 2500 eventhough both before and after the tournament he was below.
The website you link only shows what the rating was at the start of each month. He is very close to 2500 on those. But apparently at some point in the middle of a month he must have been above it.

How do you know he was above 2500?
Proof? So far we can see he never achieved 2500 rating
Since FIDE made him GM and since this situation is directly in their rules, I assume that his tweets are correct.

Yeah, as MikeGreenhill pointed out, as long as that player reached 2500 or higher at any point during a tournament, he then qualifies for the GM title (assuming he achieves his norms, as well).
He would've received a certificate from the Chief Arbiter, proving that his rating reached 2500 or higher at that point, which would've been examined by FIDE to award him the title.

When one of the requirements is to have or reach 2500 Fide Elo rating
Wait how is that possible he's only 941?
@ESP-918 if you work hard on your chess, then maybe in 5 years from now, your OTB rating might be 400 elo points below Hans'. I'm rooting for you.
