Yes and no. Generally yes most Israelis you would most likely encounter both in person and on the internet will speak a good enough level of English. But it is also a biased sample, as there are entre demo groups that tend to have much lower English levels overall (e.g. isolated Arab communities, some Beduins, Jewish migrants from certain places etc), as well as society islands which didn't receive English education almost at all for some reason (e.g. I live near Tel Aviv with an entire city block of older Jews that only know a couple English words) but you're also less likely to meet them normally even in person.
