Theft risk Poland

I’m going to Poland for 3 days and I don’t think I have a chance to put the car in a locked garage. How do you rate the risk of theft? And do you think it makes sense to use a steering wheel claw or something like that? I only heard from Polish acquaintances that the risk should be very high even in guarded parking spaces and that you can also be stolen there – or maybe just there. What is your opinion?
