No. Most of them are tourists.
Of the ones camping in Dublin, here's a google response to your question:
The information is actually very hard to get. But from the bits I have pieced together, it looks like it is mainly people who initially entered the UK legally on visas, and then travelled to Ireland via Northern Ireland. The largest number are from Nigeria. So, because these people would not have been subject to the Rwanda scheme, that cannot be the reason they have sought asylum in Ireland. Maybe it is just that Ireland was seen as a nicer place, or perhaps they want to be in the EU at the end of it all.
