7750 EUR on Wex, 7470 EUR on Kraken. Is it that easy?

Hi folks.
Question from a newbie in trading here. Yesterday my boss told me that he saw a price of 7750 EUR on Wex, and 7470 EUR on Kraken, with obvious trading opportunities.
I am a newbie, but is it too good to be true?

I mean who will buy at 7750 EUR if there is a cheaper price somewhere else?

Do you manage to get some earnings this way, or am I being naive?

Thanks for your opinions
