Becoming a pilot requires you to build skills, experience, and knowledge in a wide range of areas beyond simply controlling an aircraft. However, the biggest hurdle that most people face isn't the difficulty, but instead the high cost of this process. You need 250 hours of flight time to earn a commercial certificate, and 1,500 hours to achieve your Airline Transport Pilot certificate. Each hour of flight time may cost you $100-200 (depending on where you are in the country, and the schools and airplanes available to you), in addition to $40-80 per hour for an instructor, for the portion of time that you are receiving instruction. That is a pretty tough hurdle for a lot of aspiring pilots. The other factor to be aware of is the need to be able to receive a medical certificate. The FAA has very stringent guidelines to receive this certification from an Aviation Medical Examiner, and if you have ever experienced or received treatment for a range of common issues (depression, anxiety, etc), it can be very difficult to get through this hurdle. Always consult with an Aviation Medical Examiner, and look through the FAA's guidance on medical conditions, before you invest too much in aviation as career path.
