Maybe it's a stupid question hahaha but, should I trust in a VPN?
Go watch some youtube videos about the safety of VPNs on youtube.
It boils down to:
1. A VPN is a money making company that is by no means going to stand up for you if you get in trouble.
2. They say they do not keep logs but you have absolutely no way of verifying it is true.
3. A VPN provider knows it will likely be used by people for shady stuff, so it is an easy target or and easy honeypot.
4. By using a VPN all you are doing is shifting your trust from your ISP provider to your VPN provider.
Non TOR websites are accessed using exit nodes. Basically your connection goes through several internal tor nodes where each node adds an encryption layer and does not know the whole route. In the case of a normal website the last node is an exit node which finally sends the request to the clear normal net. So it is still safer to use than not using tor. The website sees the IP of the exit node, not your IP. On top of that following the request back through the tor route is difficult making it hard to find out who made it.
It is not impossible though and (usually governments) periodically attempt to compromise tor nodes and try to deanonymize users. But it should still take more effort since tor is an open source decentralized network than getting access to a VPN that you can simply sue.
The tor browser also does many other things to protect you from fingerprinting where websites may try to track users based on a combination of unique data like you display resolution, user agent, os version, hardware, rendering capabilities and javascript...
It all depends on what is your threat model. If it is your family/partner, using tails and keeping stuff encrypted is enough. Take a look at VeraCrypt.
If it is your ISP, you need a VPN/TOR.
If it is the government, you need to shoot your modem.
