This is a top tier super power. Ublock on Firefox and AdGuard on iPhone are pretty effective. When I actually see an ad it physically hurts.

On iPhone check out Orion browser. Blocks ads, even on YouTube. Though sometimes video quality goes low (manually set it higher to fix). Firefox focus also works, but only one tab

If on Android, check out revanced. You can remove ads from lots of apps. Highly recommend Firefox as well.

Brave is also extremely effective at removing ads while keeping websites functional (including YouTube). It even has some fingerprinting protection. (and before someone complains, you can disable all the crypto stuff)
