There are lots of things that make a whole lot more sense after you have a few hours in an airplane. For example, when you set the altimeter the altitude moves in the same direction as the new altimeter setting. You can read about it in books but when you do it a few times in the airplane, it tends to stick with you. Recently we have had some wild swings in pressure and when I got in the plane the altimeter read minus 310' instead of 168'. That’s a good example to use when teaching about temperature and pressure changes and the mantra, “High to low, look out below.”.
Likewise, understanding slips and skids makes a lot more sense if you have actually been in an airplane and stepped on the ball or changed the bank angle to regain coordinated flight. “Red over white, you’re all right.” makes a lot more sense if you’ve seen the VASI change as you approach the touchdown zone. There are dozens of little things that are asked on the FAA tests that are second nature to pilots but seem odd to someone who has only read about it books.
So yes, you will be at a disadvantage if you aren’t a CFI, but if you get some training in landing, stalls, steep turns, spatial disorientation, unusual attitudes, etc. I think you will be a better teacher.
