The 80/20 Of Exclusions On YouTube Ads: Exclude These Placements From Your Campaigns

Great information can you plz do one practical video on how to exclude Google display net work from Google ads

Medellin Colombia?

What If I'm targeting Broad audience above 45+ and only men because I'm promoting prostate product. That's my targeting. Should I exclude mobile apps and display? Because I'm losing money on both placements.
