The main thing anyone starting needs to realize is that it takes quite a bit of time to get used to how Quads fly in Acro/Rate mode. I started on a simulator (Liftoff) with an XBox pad and that was super punishing as gentle and precise control is needed. Switching to a proper radio was a night and day difference. I'd guess it took 5-10 hours of flying time to get to the point where I could comfortably go where I wanted 99% of the time. I'm up to 50 hours of sim time now and flinging the things around with wild abandon. Looking forward to summer and getting out to try the real thing.
My recommendation for starting out would be to grab a cheap radio that is easy to connect to a PC and a copy of a simulator.
Clock in 20-30 hrs of flight time in a sim using a real radio, before even thinking about building a quad.
You might realize it is not for you, and save the hassle, but more importantly it is really dangerous, even when you are an experienced driver.
Without sim experience you are guaranteed to crash quickly and do some damage in stuff and/or people!
In terms of a pc simulator I have used Velocidrone which everyone says has the most realistic physics but is not necessarily the prettiest.

It's an addictive and fun hobby for which I'm still in the initial stages of.
Happy flying!
Edit: first time posting / trying to format properly.
to have your mind blown by experienced fpv pilots, check out Nurk FPV, Johnny FPV, Mr. Steele, and Rotor Riot.
FPV is a disproportionately expensive hobby ... every hard crash can cost you between $20 ( broken motor bell) to $200 (cost of entire drone when dropped in water and electronics go poof). Still great hobby, highly recommend!
