A piece of paper proves everything.

All the transaction IDs are conveniently hidden.

This guy won all these profits back in May 2023, but this forum thread is posted now(more than half a year later). This seems kinda suspicious. Why there were no news about this guy back in May 2023?
Why does he have to mention Trustdice? This seems like a sneaky form of marketing coming from Trustdice. I have nothing against new and innovative ways to bring more customers to your casino, but such posts are insulting the intelligence of many gamblers.
It's totally possible for a guy to achieve big wins via gambling, but I can't see any clear evidence, which proves that he actually won 37K USD.
