Yah all in it ends up being more than that if you count the transmitter/controller and goggles but prices on those can get astronomical (check out DJI FPV system for an idea
or FatShark HDOs, both extremely pricey top shelf products basically). For the quad itself around $200-300 range is usually "correct" assuming pretty quality components:
FC for around $40 (one I linked is a little nicer so like $10 more there),
receiver is around $20 (for controller/transmitter signal to get received),
runcam split is about $80,
VTX is about $30,
ESCs are around $40,
motors can range depending on quality etc. but usally somewhere around $60-100 on motors

Motors for swinging bigger props are usually more expensive (as are the props themselves) so yah if looking to save some cash go with 5" or 3" build and can cut down on initial and long term costs pretty substantially.

)
"UAV futures" on Youtube does $100 build videos every year or two I think can see one of the parts lists here for that:
UAVFutures $100 Build
rotorbuilds.com
but can also see there is a big cost in goggles (because Aomway commander goggles are pretty good/premium, personally use Fatshark goggles but started with Eachine box goggles that were $50... after learning to fly with no goggles just line of sight watching it with my eyeballs
)
Guess point is cost depends on what you want to achieve and how much you want to sink into it initially vs add on later. Can get a "ready to fly" all assembled and ready to go minus the controller/transmitter

Or could get just frame ESCs, motors, FC, and receiver and fly line of sight with no camera or goggles (need to learn this at first anyhow) then can add parts as you learn (this is how I did it personally). Good thing about build from scratch is easier to fix things if/when they break since you did the initial work don't have to learn that later but save a lot of time buying pre-built too so all trade offs once you know what's what kind of up to you
