Will Duas Make a Difference When I Keep Seeing Signs About Not Getting Married?

Assalamu alaikum, I've been making lots of duas, performing istikhara, and even waking up for tahajjud, but I haven't received any clear signs or responses. Over the last six months, every single time I've made a heartfelt duaa for marriage or asked for some kind of sign, something happens. It might be through a video, something a family member says, or even a point made in a khutba-the message is always something like 'marriage isn't written for everyone, and that's their test.' The way these messages come to me is so specific and sudden, it's hard to believe it's just a coincidence. I'm beginning to feel pretty certain that Allah is guiding me to accept that marriage might not be part of my qadr. My question is, can dua really change this outcome? I've been praying about this for years. It's left me feeling sad and a bit broken, and just last night, after making another duaa for marriage, I came across the same kind of sign again. It's really disheartening.
