Someone Explain How Promos Work For New Ranked Players

EDIT: When I say promos I mean the first 10 games that give you your rank, Provisionals. I've heard someone call them promos before so I've been calling them that. I don't mean the games you play to rank up, I mean the ones you start off with. First 10

I am finishing up my first 10 games. I have never played ranked before so this is my first time. I am 5 wins 4 losses currently, overall most of my kda scores seem pretty good I think.

How exactly does promos work for new ranked players? I read something about points and I've seen people say it does count kda a little and others say it doesnt count kda. I've also read that if you got into a certain place last season you are more likely to get around the same spot this season (as in it remembers where you were and is more inclined to put you around there if you do well)

Since I haven't ever played ranked before, how does this work? Am I more likely to get put into bronze since I wasn't ranked before? Is it even looking at kda? (and it should because even though I have lost 4 games my kda really wasn't bad and I have been getting kills, I didn't feed too much except for 1 really bad game. I don't usually die too much.)

I am aiming for silver and if I lose my last game I'd have 5 wins, 5 losses, and I'm worried about becoming bronze. The way it decides where you go really confuses me.
