@Rediikid You can use APK Editor Pro or Lucky Patcher. Lucky Patcher may or may not be easier for someone like you, but in APK Editor, do a full edit on the app (and decode all) then goto the middle tab and search something like "ads" and for Google ads for example, click where the search results come in and remove the full line that has that and save. This is alot to explain but in the pic look at how in AndroidManifest.xml it shows "com.google.android.gms.ads.....". Every app is different tho.
