>Is this intended to imply that Spain has particularly high levels of sports betting

La Quiniela, a lottery based on soccer matches' results. Every middle aged man filled some weekly forms (win for locals/draw/win for foreigners) as if it was a religion. If you matched 14 from 15 results (much better with 15), you could get a big prize. Also, Jai Alai matches on the North of Spain had huge bets on results too.

Younger millenials and Gen-Zers will just play on RETA which is kinda the same as La Quiniela but online.

In practice La Quiniela works more like a lottery than betting, though. No immediacy, no lights and sounds, no adrenalin rush. I don't think there's much risk of people falling into severe addiction by playing that.

Maybe a bit out of scope for this article, but seems like in every country “Younger millenials and Gen-Zers” are turning to gambling online while traditional gambling (like Vegas) dies.

I feel like this might be a net negative from the pure speed and access in which you can lose money online vs real life, but idk.
