I was dumb in college and graduated with about $4k in credit card debt. It didn’t take a classroom lecture to realize that spending more money than I earned was not a sustainable practice. It’s also not that hard to keep track of how much you spend and make sure it’s less than how much you make.
For almost anything personal finance related there is free information available all over the Internet if you care to spend a couple minutes googling for it.
Likewise with taxes, if you have a regular W2 job, taxes are not hard, just read and follow the instructions. It doesn’t help that people keep repeating the dumb meme that if you make a typo on your tax return the IRS will immediately throw you in jail. They won’t, they just send a letter telling you they corrected it for you (guess how I know).
