loosing more than winning when starting out is normal
who do you play, which input schheme do you use, have you played other FGs seriously?
what did you read and watch for guides so far?
did you do the ingame tutorial?
I ask this, so I have a rough idea where you are.
the most important things when starting out are pokes and antiairs.
this stop people from jumping in on you and just walking in on you
then you need to learn to identify vastly unsafe moves, that you an just block and punish
a lot of people will be antsy and just wanna get in, these moves are often (but not always), unsafe
watching replays with frame data on helps identfying that
