Today I moved to Ubuntu after almost 17 years of using windows.
Every time I turn off my laptop or restart it I get this long list that keeps starting and finishing tons of things that I have no clue about. It goes on for few minutes. Is it how Ubuntu normally boots up, or something is off?

Ubuntu is not a drop-in replacement for Windows. It's different. It works differently. It boots differently.
Your question seems to boil down to "is this difference okay?" If your system boots to a working desktop, then the difference is okay.
As a new user, you are going to encounter LOTS of differences. Embrace the changes.
