Seeing how these cost north of 1500 bucks, hes quite correct with his statement
Those prices are in Australian dollars which are worth like 2/3 of USD so they are actually pretty cheap.

There are some good looking gaming laptops on sale right now. Last time I bought a laptop that looks good I made a thread complaining that it performs like shit.
The one I’ve got my eye on is the Dell G3 15. Will it be able to run The Witcher 3 and Sekiro: Shadows die twice on high settings at 1080p 60fps? Is there anything important I should know before buying one?
Will they ship it to Greece though?
General rule is a 1050 Ti will handle current games at 1080p@60 well. But that's the rule for desktops, the equivalent GPU in a laptop will perform maybe ~10% worse (assuming it gets adequate cooling), not enough to make a big difference in FPS though.
In my experience, some games are too demanding for 1080p60 on my GTX 970 but are still fully playable with ~40 FPS stable on high/max settings. Notably Ark which is very demanding, but I think it might be CPU bottlenecked as I'm still rocking an i7 920. Atlas runs like shit but that game is poorly optimized.
And according to benchmarks, the 970 is much faster than a 1050 Ti.
So with that in mind I would suggest a GTX 1060 minimum if at all possible, which according to benchmarks is slightly faster than a 970, it will give you more leeway to run demanding games. But those games you suggested should probably be fine, surely those are not the only games you intend to play though.
All that being said I really
would not recommend a gaming laptop unless you really need one because 2-3 years down the line it's going to be trash at running new games and you can't do anything to upgrade it, besides get an eGPU if the laptop supports Thunderbolt, and those are expensive and bulky. It's just money out the window. But if you are going to be traveling or going away for a while and you need a gaming laptop for that, or you need a powerful laptop for other things while you're travelling, then and only then should you buy one.
This gaming laptop was top of the line (HD 7970M) when I bought it, maybe 6 years ago now, still runs many new games fine but it only took 3 years before I started noticing it struggling with some newer games (not running it acceptably in my opinion with sub-30 FPS)
The HD7970M is actually slightly faster than a 680M which was the other option available for top-end gaming laptops at the time but for a much higher price.
The 1050 Ti and even the 1060 are far from top-end, they are not going to last long as they are only just about capable of 1080p@60 on high settings currently and nothing higher. And don't think you can just turn the settings down to medium/low and keep using it for gaming for 5 years or more, in my experience turning down the settings only gives a few extra FPS in many modern games, which doesn't help when the game runs at 15-20 FPS.
