1.Ski is more basic for a beginner right? so i suppose i go to a resort I'd be more likely recommended to ski than snowboard, is that right?
Are you asking if the resort will try to push you into skiing instead of snowboarding? The learning curves are different, but generally after 3-4 days on a board with lessons you will be able to link some turns and start "snowboarding".
2.Is this "Hobby" more of a once in awhile thing? that's at least what i understood, unless your a professional or live in a resort
Here's the big question: Are there any mountains available near you? Looks like Mount Hermon is open Dec-March or so.
I get out 30+ days a year over a 6 month season, so an average of 5+ days a month. That's more than a hobby to me!
3.Is it fun? meanwhile the main thing that attracted me to it is the freedom (i think at least) the feel of the wind at your face and also everything white, (i love snow and plain and white stuff) and also more but a little bit more private
Only you can figure that out for yourself. Some people try it and get discouraged quickly. I started 22 years ago, and will likely snowboard until they're transporting my body to a funeral home.
4.Is this "hobby" expensive? compared to motocross atleast, how much could a basic kit with everything needed can cost? (i speak way to early, i live in a movie)
It's not cheap, though it can be. I can only speak in Canadian $, but you could convert (or do the google searching yourself). A full setup will be at least $1000. And when I say that, I mean a used board, used bindings, new boots, helmet, gloves, jacket, pants, goggles, etc. You may be able to get it cheaper, but it'll likely be more than that. Once you've bought that though, you can likely get away with only replacing 1-2 things a year (goggles, boots every couple years, etc.).
Lift tickets in Canada can be anywhere from $40/day to $115/day. No idea if/how you can get discounts from your local hills. Once you've got a few seasons under your belt, there are way of making that cheaper if you join a competition group, ski patrol, instructor group, etc.
Travel costs to get to the hill add up quickly, hotels, meals, etc. The cheapest you can snowboard is to live beside a hill and have a season pass. Passes and travel will almost always cost way more than gear each year.
I would say go for it, if you've got a hill close enough to travel too a couple times a month. You need regular practice to get good enough for it to be worthwhile making a trip to the LARGE mountians...
