How does the presale Lottery System work?

Soo I’m trying to grab a ticket for Doja Cat in Yokohama through Ticket Pia presale, and honestly the whole lottery thing is confusing. I thought I understood it, but the more I look at it, the more questions I have. Hoping someone with experience can help!

Here’s what I’ve figured out so far:

You pick your section (like GOLD or S) and the number of tickets (I only want 1).

Then there’s a “preferences” thing where you can pick up to 6 sections in order of choice.

There’s a note saying “you’ll only be selected for one performance,” and a little star that says because it’s a lottery there’s no guarantee and your money is refunded if you don’t get picked.

My questions is if I put GOLD seat as my first choice and S seat as my second, I’ll only ever get one ticket, right? Like it won’t randomly give me both if I “win”?

Basically, I just want one ticket and want to understand the lottery from start to finish so I don’t screw it up.

Thanks in advance!
