How do I improve my game?

I am a 22-year-old college student. As you can tell by the title I am not very good when it comes to talking to women. I have social anxiety so talking, in general, can be hard for me. Over the past year, I have hung out with 4 girls and all have ended in such disappointments, to say the least.

1) I asked this old friend from high school to a bar and she agreed. I don't drink very much since most of my friends don't drink but decided a bar could be good since its an adult hang out type of thing. The night went off to a rocky start since I didn't know that vertical IDs weren't allowed in bars in my state and the bartender was hesitant to serve me but he did so anyway. I got tipsy so I had this new confidence about me but I saw that she really wasn't into me so my drunken stupor I decided to ask this girl for a kiss and she told me, no and I left. Cringe plagued me for a while.

2) I asked another old friend out for coffee. We got caught for a bit and then drove around my city. I got a couple of hits of her wax pen and I got high. She started talking to me about her sexual experiences with her friends. Then we made out for a bit but it was bad and really weird. I guess I'm a bit rusty because I used too much tongue and hadn't kissed a girl in years before that. She stopped and told me she wanted to go home and I left too. In hindsight, I probably would have never done this if I wasn't high but it was embarrassing and I regret it. Cring still plagues me.

3) I asked this girl to hang out so we hit a tea bar and an actual bar. The night went smooth all things considered. She wanted to go home so we head out to the parking lot. She asked me if she could see my car which I thought was odd but I showed her the inside of my car anyways but I didn't think much of it. In fact, I thought she wasn't interested in me because she wanted to go home and so I never hit her up again.

4) I met this girl in one of my clubs in college. We worked on a project together. She would Snapchat me things that reminded her of me and would text me when I did something funny for club presentations. One time she snap-chatted me a pic of some beer. I told her jokingly "it's too early in the week to get crunk" and she said, "yeah we should definitely do it on the weekend or something". I always thought she was just agreeing with me but I have been told that I should have just asked her for drinks. I missed that chance but a couple of weeks later I ask her to go hiking with me and the day went great. We talked had some nice convos and but I never made a move. Sometime later I ask her to get some burgers and she agrees. The night goes well and I offer to pay for the food but she says no. We then hang out at some store before she has to head out but it was a fun night all things considered. Since then due to quarantine, I haven't been able to hang out with her for months and have only spoken about club stuff. To this day idk if she liked me or was just being friends.

So how do I improve my chance of finally sealing the deal? Or am I fated to keep on failing?
