This isn't true.
In practice, you do what you're comfortable with and what your practice wants you to do. Often, that can include lines, biopsies, and drains. That's low hanging fruit that IR doesn't want to deal with.
I'm likely going to match IR, but I wanted to know which programs do ablations, kyphoplasty , etc. because at the very least, I want to do some procedures. Some days, I really enjoy diagnostics to the point that I think I'll miss it...But ultimately, I think I'll do a body heavy fourth year and IR fellowship. The practice I'm talking to is perfectly fine with us reading imaging in addition to procedures.
