So, when asking yourself "could I get tracked" think about who might track you.
Signal... probably wont. They see you are using Tor (some exit node that a lot of others will be using too) and thats it.
The tor circuits change all the time too, so yes some server you connect to sees your IP, and if the same malicious person behind that server may also control a backend for an app you use, they might be able to track you with that.
But this is only likely in specific scenarios.
Tor is way better than selfhosting a VPN server, poorly. Public VPNs are now blocked often, selfhosted are even more unique than being at home with multiple people in your LAN though.
And as a selfhosted VPN doesnt change, this is perfectly identifiable. So Tor is not a problem, a selfhosted VPN will be. A public VPN is also less likely to be, but it may not switch servers for days (auto-reboot) as VPNs are not made for privacy but for a stable and secure connection to a LAN.
