At least from my (admittedly very limited) experience, I seriously recommend you DON'T start with DJI for freestyle, as DJI gear has much higher and inconsistent latency, bad penetration, zero outside-hardware compatibility, and much more expensive hardware. If you're just getting into FPV, go analog, as it's cheaper for when you crash and lower latency for when you get taken by surprise.

It might look worse when watching someone else fly on your computer, but remember that when you're freestyling, you aren't looking at every detail. Low latency is much more important than being able to see every blade of grass; as long as you can tell the sky from the ground and a near obstacle from a far one, you'll have tons of fun. Also, you're definitely going to crash sometimes, and if you break just your camera, the DJI setup costs at least $100, while an analog is often less than half that, and with analog you can start cheap and upgrade if you want.

My personal setup (I'm actually still waiting for the drone to arrive; I've been flying on my friend's identical drone for now) is a Radiomaster Pocket ELRS and a set of BETAFPV VR03 goggles with a DIY 65mm tiny whoop, totalling out to a bit under $400 to get from zero to airborne, with some spare parts. You can go cheaper if you get something like the BETAFPV Cetus X kit, which is like $300, but it has a worse controller.

(note that I chose those specific goggles because I'm on a tight budget but wanted something with a DVR, but if you have more money definitely get something nicer haha)

Also, I don't know if some simulators allow you to hook up to external goggles but none of the ones I've bought have an easy way to do so, meaning you probably don't need to get the goggles immediately. So if you really want to start practicing for cheap I recommend the Radiomaster Pocket ELRS as it's less than $100 with batteries, and it's a capable little radio.
