Is an Intel® Core ™ i7-3630QM processor with nvidia geforce gt 650m good (Is it sufficient for e.g. Blender, Minecraft)?
No, not really. The i7-3630 is very old, but when it was released it was a high-end processor. The GT graphics unit is too weak to really play. Minecraft is probably running.
Please use tower PCs for gaming. Laptops get warm, are slower than the specs, and very expensive. (Own painful experience)
You could put together a good tower for the money.
Apart from that, this CPU / GPU combo should be sufficient for Minecraft, but you should have enough RAM.
Beyond Minecraft, unfortunately, nothing will be gambled on.
I would upgrade the pc to 32 GB ram: /
Doesn't make it better since the 3630 can only do DDR3.

Wait, do you have this CPU + GPU in a tower? You already know that these are mobile (= rather bad) units.
32GB are stable.
In a notebook…
That doesn't bring much, to be able to play more than Minecraft needs a better CPU.
Because you write "PC", that's why.
Well, Minecraft will surely go.
If you scroll down enough we get game benchmarks to the GPU

32 GB RAM will not change anything, I would install a maximum of 8, more is not worth it
I take 16 Ram: / But is it enough for Minecraft 60 mods?
I think it will run at least 1366x768
