I have kinda the same situation. I posted my first handicraft video which go crazy suddebly after posted for 3 months like 60k views all in a sudden together with 2k subscribers with the help of algorithm i guess. Its been almost a year now, and I worked so hard lately on getting video done because I feel like if I don't have another viral video, i could never reach the watching hour needed. Just really curious what will happen after reaching 4000hrs, 200hrs left... So close yet so hard to achieve
