AITAH for no longer wanting to attend my siblings' sports events?

I am 20 years old still living with my parents. One sibling (just became a teenager) plays competitive baseball while the other (below 10 years old) is a competitive dancer. I would go to their events almost every time prior to this year as I had a lot of free time and didn't feel like I had the type of independence I am trying to have now. When I would go to these events, I would be the only person around my age group as everyone was either too old or too young, but this didn't bother me. The younger kids would play video games on my phone while I taught them, so I at least had some fun. Though this is beginning to change. I was unemployed until recently and just turned 20 so I feel like I'm in an odd position where I don't want to hang out with the younger age group while I'm still too young to really bond with the parents. Is it weird that I feel this way? It feels odd being the only 20 year old.

Edit: I'd like to add that my dad took offense when I told him that their friends are not really my friends, and that I don't have that type of connection with them.

Building onto this point, I am in a chapter of my life where I am finding myself. I have been looking into becoming a paramedic, but have been having some doubts. I have just been looking into careers, and working to save money for potentially going to college.

My family does this thing where they'll try to be there for their friends' kids' events so they'll leave to go on a day where my sibling doesn't even have an event going on yet. An example of this is where my sister's friend has a dance on a Friday, and my family will still go even though my sister doesn't dance until Saturday. It's nice that they want to support them, but I myself don't want to spend an extra day there if my sister is not dancing that day, especially since I'm not close with anyone there.

I have many friends and a girlfriend, and while I am able to hangout with my girlfriend often, most of my friends are busy and the few times they are able to do so happen to fall onto my siblings' events.

There is also the traveling. Most of these events are at least an hour away, and with gas prices being so high, my parents book a hotel. I do not like hotels. I like sleeping in my own bed and in the comfort of my home. My sister's competitions almost always require my family booking a hotel. If they were close enough where it was just a half hour away, then I'd be more willing to go. My brother's games will have many that are close, so I will be going to those, especially since they won't be taking up the whole day.

Please let me know if I am TAH, and I appreciate your time.
