First time getting my own plan (dental) and I'm confused

Hi! I already know I'm probably going to sound stupid but I'd rather sound stupid and get help than make the wrong decision and regret it. I was kicked off my mom's insurance in December because I turned 22, so I have to get a plan for myself. I know I should've already picked out a new one because it's been 2 months but I'm worried about messing up so I haven't been able to make a decision. I still have BCBS as her dependent, that just doesn't include dental/vision, which I need. I looked at aetna because that what she has/what I had as her dependent, but now I'm confused about the differences between insurance vs a savings plan. I asked her about it and she agreed that they sound like the same thing but worded differently, except the savings plan is a lot cheaper and includes more than just dental. So I guess I'm asking someone to help dumb it down for me to understand? lol idk. I'd also appreciate any advice/tips/pointers in general (including if I should use setting other than aetna) because I'm so lost. Are the savings plans cheaper because you're supposed to get one on top of having an insurance plan? This is what the website says:
