I think it means that people feel chained down when they are born into one lifestyle, and what Natalia says 'But god we almost had it all' she might be referring that some people come so close to success, but are restricted due to lifestyle, past experiences, etc. And at other points in the song when she says 'Devils don't fly' and then immediately follows with 'But I tried' she might be referring to how people are coming into access of another opportunity and when the last 'But I tried' comes around at the end of the song, she (or who she is talking about) has finally reached the success or opportunity they have been looking for. On a side note, when she said 'Angels were never meant to fall' I believe she is saying that even though a person works so hard and shouldn't have failed when they worked that hard, they often end up failing anyway due to, yet again, background, lifestyle, etc. I would just like to say this is simply my opinion and you can choose to believe what you want, but this is to an (almost) full extent what I believe the song means. Have a good day, this had been L. M. Asaaena.
