The only way to get better is to practice.
Take a look at how you play, and which skills you use. The skills you don't have or can't use reliably are why you're losing fights.
The easiest playstyle is just to beat on your opponent without any real strategy. You'll take plenty of damage, but probably win if your characters are stronger.
The first skill most players develop is to get the hang of Parry. Following that, crucial skills include (but aren't limited to)
Dexterity
Intercepting dash attacks
Backdraft intercepts
Re-Parry
Baiting Specials
Most advanced is to be skilled at all of the above; and to have developed an understanding of how to strategize in a fight:
Can I parry this guy? Will my parries fail? How do I bait Specials when I can't hit into their block? Why does everything go wrong when I'm fighting Domino?
The best place to start learning this stuff is by watching some of Dorky Diggedy Dave's stuff on YouTube:
