I already have heared about Bottles sandboxing capabilities, but, how this differs from standard Flatpak sandboxing system? Is really secure execute any Windows Software using Bottles? (yes, every machine have his vulnerabilities blah blah)

As others have said, no it's not really secure.
But you could always use something like Firejail or Bubblejail to properly sandbox your applications. Also, using technologies like SELinux or AppArmor helps improve your security profile and could protect you against unknown/future exploits.
But most importantly, the best security measure you can take is keeping your system up-to-date, especially kernel updates. Unfortunately, if you're using some small-time distro, they may not update frequently or may not be as quick to respond to security incidents. Even some old-time reputable distros have been pretty bad at updating, like Linux Mint for example.
Also, consider using an immutable distro for added security, preferably one which has SELinux enabled and configured out-of-the-box, such as Bazzite.
I forgot Firejail and Bubblejail. These are good tools. I mean, only need to learn use it xd But actually sounds good.
