You dont need a bunch of expensive gear to test if you like this at all.  I'd recommend hiking with a friend in a overnight or weekend trip. Try to rent or buy used gear to keep prices down at first.   See if you like it...if you do the right gear, if you dont big loss.  First hike in the summer so you dont have the extra expense of winter gear and weight.  You can test your endurance in a gym, your taking a trip down the hiking lane for a reason...Nature 🙂   If you are really looking for being resourceful in the wild, you may want to look into a survival camping class.
