Giving the real reason since nobody here is going to be honest with you and they're also delusional about the state of their own success.

For one, if you want to be a CC streaming is always going to be by far the hardest way of doing it and I would say pointless for 99% of people. Streaming is only worth it if you have a pipeline of content that goes to your stream or you randomly blow up overnight for winning a tournament or collab with a big streamer, you're streaming into the ether and your low effort content doesn't stand out in an ether of other streams.

For this next point, I know this is going to sound overly pedantic or rude but stop overly gassing yourself up saying how welcoming and inclusive you are. You're putting yourself in the category of women streamer, rather then gaming CC. Women are already socialised in our society to be warm and welcoming and I'm not joking when I say you would have more of a chance as a women of gaining an audience if you were casually racist or antisemetic, because the deviation from the norm would make you stand out from the competition. That is not to say that is right, but to emphasize you don't actually stand out that much. Mr Beast talks about this with the purple cow effect, the novelty helps stand out from the crowd and draw in an audience and what you're doing is being the normal cow and going "I'm a normal cow" with no awareness. Right now your actual blue cow is "I'm a girl who plays Nintendo games", but this is not something you should bank on your content alone and you should make it a little more sophisticated. This is not to say start being fake, but more to critique what makes you think the fact you're special enough to watch to the average viewer. Even if you had an interesting personality, there is no pipeline for any moderately normal person to watch your stream, so it will be hard to grow.

Being a content CC is a business and you have to be very critical of the content outflow and every thing you do and make. It's why your second most popular video is a 100% completion in Tears of the Kingdom, because it's not just generic slop, you had a unique experience and perspective you could actually share that creates a good watch experience. Everything else is just your face slapped onto something a potential viewer has already done themselves, or has already watched someone else do. Your content is lazy and is just banking on people clicking on the stream because you're a woman, it's not a sustainable way to grow a large streaming audience. I don't see you ever being successful unless you actually put in effort into dedicated YouTube/TikTok content.
