My earliest videos (2013) were filmed on a Sony camcorder, from the 1990s. My newest vids are filmed on my phone. The current phone camera is so much better. Even a mid-priced phone, that is a few years old will take good video. There are a lot of channels that use their phone - after all the best camera is the one you have with you. I have a big clunky Fuji that has not left the house in probably 7 years. It takes better pictures (not video) than my phone, but is too much hassle to carry.
Content and personality are more important than your gear. You do want the best video quality you can get, but super expensive gear will not fix bad content.
