>he receives 4000+ applications on a job and nobody in Europe should consider this career

Why would you assume he's trolling? In some EU countries the market is insanely competitive due to great free schools churning out coders like crazy due to the tech hype, plus tons of skilled immigrants from developing nations trying to break into the market, so companies are very picky since they get bombarded with applications, so people with little experience or failing the culture fit or whatever arbitrary metrics are used, can easily fall through the cracks and not find a job despite being talented.

The high demand you hear is true, but only for experienced seniors and, since nobody wants to take in juniors and train them this creates a bottleneck of artificial scarcity despite the high supply of less experienced devs.
