You buy a cheap controller (RadioMaster TX16S is the best value for money right now, at $120ish, but you can do quite well with a $30 FlySky), some goggles ($40 for some Eachine EV800D, I forget the exact model number), $150ish for a low-end starting 5" quad, and $30 for a 4S battery.
I might also recommend getting a tiny whoop instead, those are very small drones for inside the house, they are super fun and you can fly them whenever you want, vs having to make a trip to a suitable location.
That should get you started. Nowadays I much prefer acrobatic wings, though, I made a Flitetest Versa from Depron foam for like $30 and it's amazing fun.

House yes, anywhere with a fire suppression system _NO_. The little glass bulbs used in most of them don't react well to having a drone bump into them. Buddy of mine had this happen where he worked not long ago, you really don't want to be that person...
Don't order from Banggood. It takes weeks to arrive and is likely to be a knockoff. There are several US retailers like RaceDayQuads.com, GetFPV.com, etc.
