Yes, good planting soil is balanced so that it allows for good drainage with the right amount of water retention (not too much, as you can get with clay soils, or too little, as you can get with sandy soils.) It is also usually tested for fertility and is amended to make sure it has the right nutrients for good plant growth. I recommend asking for a planting mix that is designed to be used in vegetable beds (not just ‘top soil’ which is sold often sold at garden supply yards, too.) However, if you really want to use the soil you have at hand on your property, you can defintely amend it by adding a lot of organic matter – good compost and decomposed leaves are great; worm castings are great if you have those, too. (I keep a worm bin so that is an easy add for me.) Organic matter improves the structure and drainage of soil. Finally, add a good granular organic fertilizer to it all, and mix it well. Each fall I make sure to add more organic matter on top of the beds. I dig this in each spring, along with another application of an organic fertilizer. I also keep chickens, so aged chicken manure is a great addition to my beds. Whether you start with a purchased planting mix or create your own, you still need to be sure feed your beds each year. I hope this is helpful!
