Yeah, the main way to get medals is from doing events. Selling plats for medals aren't ideal, especially for beginners, unless they are a duplicate of one that can't be evolved.

Occassionally, packs bought with Crowns come with a plat medal, but those are pretty uncommon. There is a once per player deal where you can purchase 5000 Crowns with IRL money and you get 4 plat medals, enough to exchange for a plat unit, so that is likely what most new players with plats did.
