Best Ad Settings for Gaming?

I tried running campaign within Gaming interest but im getting very Low quality likes from people who i think have never ever touched a game. I know im doing something wrong. My target should be PUBG and Dota users. I even add these categories in Interest but its just not working. Any help would be appreciated.

You should target 1m+ audiences, if its a ecommerce you could also narrow the audience with "Engaged shoppers". Thats my recommendation. Also use video as the creative or GIF.
