Going pro is my dream/goal man. Idk if it's even realistic but I don't care. I'll be damned if I don't do everything possible to try to be the best rugby player in the world one day
Being the seond biggest sport in the world, there are quite a few pro leagues out there. Some are obviously smaller, less competitive, and lower-paying than others, so I'm not surprised that some pay as low as 30g per year. I think that minimum salaries in the biggest leagues (such as super rugby in new zealand/south africa/australia) are 6 figures though. No rugby players are making money like elite nfl or mlb players though.
I know there are also big pro leagues in europe like you said, and japan, just off the top of my head. The captain of the usa international team plays pro in japan. There's gonna be a pro league here in america starting play next year too, although I can't imagine its players will be making much, at least at first.
It would be a dream come true to make any kind of living playing rugby.
