There is certainly a lot of wisdom in "start early" - so I encourage all my younger friends to start investing as soon as they get that first steady job. And regardless of age, there is also wisdom in keeping a good chunk of cash around - even if it just makes you sleep better, it is worth it.
If you are not comfortable taking the reins yourself, it certainly makes a lot of sense to hire a profession...as long as you are comfortable that the advisor is a fiduciary who agrees and demonstrates the will to put your interests first. There are a number of education opportunities for those that do feel like they want to learn more - ultimately nobody will care about your money as much as you will, so getting a baseline knowledge built isn't a bad idea. 🙂
