Can somebody explain to me the rules or anything why I had a draw game even when my time expired and I am up by some pieces.

In chess, there is the concept of "sufficient mating material." In order for a player's pieces to be considered sufficient mating material, they need to be able to force mate (with or without the king's aid) on the board when facing off against a lone king. Here's a brief list of what is and isn't sufficient mating material:
Queen - sufficient.
Rook - sufficient.
Two bishops - sufficient.
Bishop and knight - sufficient.
One pawn - sufficient.
Two knights (and, consequently, one knight) - insufficient.
One bishop - insufficient.
As long as your opponent meets at least one of these requirements, it is considered sufficient mating material. Why does this matter? Because a player who runs out of time will only lose if their opponent has sufficient mating material. If the opponent doesn't have sufficient mating material, running out of time will result in a draw.
I hope this clears your doubts!
