I'm definitely not the best, but I'll give the best advice I can.
1: Learn opening principles. They're very important. Make sure you know them when playing. (I'm sure someone else can give more knowledge here, I'm terrible at explaining things.)
2: In your games, you moved your f2 pawn. Don't move it. It can lead to early checkmates, and it also opens up the king to diagonal attacks.
3: When starting for the very first time with no knowledge (at all), I would say get familiar with the pieces, and how they move. Try to also become familiar with the chess board itself. Learning the coordinates will be very helpful.
I'm sure other people have more helpful advice, but this is the best I can give. If you have any questions, I'd be glad to answer. ^^
