Bischop and a knight a compensation for a rook and a pawn?

I was playing on the Play Magnus App, and after jumping by more than a decade I played Magnus 22. I have done that before and it crushes me from the very start, but this time I survived with equal material loss of a pawn. Fairly sure we were in the middle game, when I tried something. Here's where it gets tragic, I calculated and I was losing a rook and a pawn while I had it's Knight and a bishop. But in calculating I, for some reason - probably stress - assumed I was losing a knight too. I resigned, and later realized the situation, later realized the positon through an engine, and yes only a rook and a pawn. I feel like crap. was I really doing good?

There's no way to answer that. Some positions with equal material are completely lost.

Sure, in that position I like black. White's rooks aren't so useful without open files, and black has the bishop pair and no important structural defects. White's a bit passive.
