Hey dang,
i think it is really possible and a healthy start. Transitioning from freerolls to a professional poker career involves a long, dedicated path of continuous learning, disciplined bankroll management, and significant skill development, rather than a direct path. Freerolls offer a zero-risk way to learn and practice, but they are unlikely to lead to substantial winnings; instead, you must progress to real-money games, study advanced strategies, learn to manage your funds effectively to survive the game's inherent variance, and consistently play against better opponents to improve your game.
I wish you the best,
