A quick summary of and guide to IP ratings:
IPyz
y is for dust
5 means dust gets in but it still works fine
6 means dust can't get in
z is for water
5 means you can run it under the kitchen sink
6 or 9 means you can hose it down roughly in the back yard
7 or 8 means it'll survive in shallow water for a short while
An extra K on the end means a bit tougher
Anything less is less, more doesn't exist.
If either one is an X it means they didn't test that.
If they claim more than is mentioned here, it might be true but the code doesn't guarantee that.
These interpretations are approximate and not literal.
If this doesn't help then you have something weird and you're gonna have to actually read this table: en.wikipedia.org/wiki/IP_Code#Code_breakdown

Well if I had to give an interpretation I'd say 3 means you can safely use it in the rain and 4 is similar but a bit tougher
But with that said I've used a few phones in the rain and in humid rooms where touching it leaves significant condensation and not had any issues so I feel most devices are probably ok with this even with no formal rating provided you don't explicitly try to soak open ports, etc. Hense why I feel the lower ratings don't add or tell you much
