Friendly advice: you just need to stop the nonsense on this forum with your spamming of numerous threads about your potential career. There's a great thread that you started that would be the appropriate place for your additional questions.

Considering that you do not even have a private license yet, or a degree, or really any other qualifications, you can rest assured that the landscape will have changed by the time you are ready to transition to a regional, and then again by the time you are ready for a major. The one constant in aviation is change.

Sincere interest and focused motivation can take you far in this industry so keep that up. But....you haven't even started step 1 of about 100. Keep your eye on the ball and get plugging on the first steps. Every single professional pilot has been in your shoes.
