Apparently the bonding in AgI and AgCl precipitate is just an extremely polarised covalent bond; this is because ionic compounds are soluble but AgI and AgCl are insoluble, therefore they only APPEAR ionic (because non-metal + metal).

Is this true?

Well, as a matter of fact, not all ionic compounds are soluble:

Here you can see, under the "solubility" column, that all chlorides, bromides and iodides are soluble, EXCEPT for those with particular positive ions, including silver.
Hope that answers your question!

Tbh I haven't done much Chemistry in a while, so if you've already taken all this into consideration and are getting at something much deeper, then idk

Solubility is relative. so you learn ailver halides are insoluble but did you know silver iodide has lower solubility In WATER than silver chloride. the same is true in xs NH3 (common prctical test for anions)

Just depends on what level answers you are seeking. the a level explanations may involve a hess cycle.
