Hello, mate.
First off, are you sure you want the pain of golf in your life?! If so, yes the American Golf starter experience will help but they’re essentially salesmen and will try their best to fleece you.
I bought a full set of clubs, with a bag, balls and tees off eBay for about £50 when I first started. The lads at the course were ripping me as my gear was proper old. It worked for me, though. I slowly upgraded clubs one at a time, buying used stuff online until I got to a decent handicap (mid 20s) then I treated myself to a new set of irons. I’ve been playing a while now and I still buy used woods, as I can’t bring myself to use pay the extortionate prices for new ones.
I buy lake balls off eBay also, as you don’t feel as bad losing balls you’ve paid less than a quid for.
It just depends on how into it you want to get, but I’d suggest getting a cheap set to begin with then upgrading as you go along.
Hopefully, you enjoy it
